Complete Overview
The Medical College Admission Test (MCAT) is a computer-based exam owned and administered by the Association of American Medical Colleges (AAMC), and nearly every MD-granting and DO-granting program in the United States and Canada requires it. Standard registration costs $355, the AAMC Fee Assistance Program reduces that to $145, and examinees testing outside the United States, Canada, or US territories pay an additional $130 international fee that the AAMC does not refund on cancellation. The AAMC sets no coursework prerequisite: you are eligible to register if you are planning to apply to a health professions school.
The exam has four scored sections. Chemical and Physical Foundations of Biological Systems runs 59 questions in 95 minutes. Critical Analysis and Reasoning Skills (CARS) runs 53 questions in 90 minutes. Biological and Biochemical Foundations of Living Systems runs 59 questions in 95 minutes. Psychological, Social, and Biological Foundations of Behavior runs 59 questions in 95 minutes. That totals 230 questions and 6 hours 15 minutes of testing time. Add the 4-minute test-day certification, the 10-minute optional tutorial, two 10-minute breaks, one 30-minute mid-exam break, the 3-minute void question, and the 5-minute end-of-day survey, and total seated time reaches roughly 7 hours 30 minutes.
Each section is reported on a 118 to 132 scale, and the four section scores add to a total from 472 to 528. There is no passing score. Wrong answers are scored the same as blanks, so leaving a question unanswered gains nothing. The AAMC converts raw correct counts to scaled scores through equating, tailored to the specific form you sat, and it takes 30 to 35 days to release results.
The percentile table in effect from May 1, 2026 through April 30, 2027 is built on 305,494 scores from the 2023, 2024, and 2025 testing years. Its mean total score is 500.6 with a standard deviation of 11.2. On that table, 508 sits at the 74th percentile, 512 at the 84th, 515 at the 91st, and 520 at the 97th. For the 2025 entering class the AAMC reported 54,699 applicants and 23,440 matriculants, with a mean MCAT total of 506.3 among all applicants and 512.1 among matriculants.
Attempts are capped. You may sit the MCAT no more than three times in one testing year, no more than four times across two consecutive testing years, and no more than seven times in a lifetime, counting from the April 2015 administrations forward. You may hold only one appointment at a time, and a 24-hour waiting period follows each exam before you can register again.
Most candidates build a preparation block of several months around the AAMC Official Prep catalogue, because those items come from retired and pretested AAMC material. The AAMC store sells full-length practice exams at $35 each, Section Bank volumes at $45 each, and an online-only bundle listed at a $390 regular price. The free Khan Academy MCAT Collection, hosted through the AAMC, carries 1,100 videos and 3,000 review questions.
Why Get MCAT Certified?
Nearly every MD and DO program in the United States and Canada requires an MCAT score, and the 2025 cycle drew 54,699 applicants competing for 23,440 first-year seats.
The score gap between the average applicant and the average matriculant was 5.8 points in 2025: 506.3 versus 512.1, on a scale whose standard deviation is 11.2.
Percentile movement is steep in the middle of the scale. Moving from 500 to 508 lifts you from the 48th percentile to the 74th, a 26-point percentile jump for 8 scaled points.
One registration fee of $355 covers the exam and score distribution to schools, so there is no per-school score reporting charge on top.
The Fee Assistance Program cuts registration to $145 and adds AAMC Official Prep material at no charge, a saving of $210 on the exam alone.
Scores stay usable for two to three years at most schools, so a single strong result can support more than one application cycle.
The seven-attempt lifetime cap means each sitting has real cost, which pushes candidates toward one well-prepared attempt rather than repeated trials.
Exam Format & Structure
Duration
375 minutes of testing time (6 hours 15 minutes). Total seated time is about 7 hours 30 minutes once the 4-minute certification, 10-minute tutorial, two 10-minute breaks, 30-minute mid-exam break, 3-minute void question, and 5-minute survey are added.
Questions
230 questions across four sections: 59 in Chemical and Physical Foundations, 53 in Critical Analysis and Reasoning Skills, 59 in Biological and Biochemical Foundations, 59 in Psychological, Social, and Biological Foundations.
Passing Score
None. The MCAT reports a scaled score, not a pass or fail result. Sections score 118 to 132 and the total runs 472 to 528, with a scale midpoint of 500 and a 2023-2025 examinee mean of 500.6.
Question Types
- Passage-based multiple choice with four options. Each science section carries 10 passage sets of 4 to 6 questions.
- Discrete multiple choice. Each science section carries 15 standalone questions that reference no passage.
- CARS passage sets. Nine passages of roughly 500 to 600 words, each followed by 5 to 7 questions, with no discrete questions.
Delivery Method
Computer-based at Pearson VUE test centers. Check-in includes signing in, presenting valid ID, a digital palm scan, and a test-day photograph. The AAMC issues a noteboard booklet and fine-point marker for scratch work.
How scoring works
Score scale
Each of the four sections is reported from 118 to 132. The four section scores sum to a total from 472 to 528, with a scale midpoint of 500.
Score needed to pass
None. The MCAT has no pass mark. For reference against real admissions outcomes, the AAMC reported a mean total of 506.3 for all 2025 applicants and 512.1 for 2025 matriculants.
Roughly what that means raw
The AAMC does not publish a raw-to-scaled conversion table, and states that the conversion changes from form to form.
When results arrive
Results are released 30 to 35 days after the test date. There is no unofficial score on test day. Percentile ranks attached to your score refresh every May 1 using the most recent three testing years.
How the scale is built
The AAMC converts the raw number of correct answers into scaled scores through equating, a statistical adjustment for small difficulty differences between test forms. The conversion is tailored to the specific set of questions on your form, so it is not a fixed raw-to-scaled table. The AAMC states the exam is not curved against other examinees on your test day. Wrong answers are scored exactly the same as unanswered questions, so there is no deduction for guessing. Scoring is compensatory across sections: a strong section offsets a weak one in the total.
Pacing and time budget
230 questions in 375 minutes gives you 1 minute 38 seconds averaged across the whole exam. By section: 1 minute 37 seconds in each 59-question science section, and 1 minute 42 seconds in CARS. per question.
32 minutes into section 1 (Chemical and Physical Foundations)
About 20 of 59. That is roughly three passage sets plus a handful of discretes.
95 minutes (end of section 1)
All 59 Chemical and Physical Foundations questions, with nothing left blank.
185 minutes of testing time (end of CARS)
All 53 CARS questions. Nine passages in 90 minutes means 10 minutes per passage including its 5 to 7 questions.
280 minutes of testing time (end of Biological and Biochemical Foundations)
171 of 230 questions. Two of the three science sections are done and the 30-minute mid-exam break is behind you.
375 minutes of testing time (end of Psychological, Social, and Biological Foundations)
All 230. The void question follows for 3 minutes.
| At this point | You should have answered |
|---|---|
| 32 minutes into section 1 (Chemical and Physical Foundations) | About 20 of 59. That is roughly three passage sets plus a handful of discretes. |
| 95 minutes (end of section 1) | All 59 Chemical and Physical Foundations questions, with nothing left blank. |
| 185 minutes of testing time (end of CARS) | All 53 CARS questions. Nine passages in 90 minutes means 10 minutes per passage including its 5 to 7 questions. |

| 375 minutes of testing time (end of Psychological, Social, and Biological Foundations) | All 230. The void question follows for 3 minutes. |
- In the science sections, the 15 discrete questions are faster than the 10 passage sets. Many candidates sweep the discretes first to bank time, then work passages with a known remaining budget.
- CARS runs on a passage clock, not a question clock. Ten minutes per passage is the ceiling; running 11 minutes on passage one costs you a whole question at the end.
- Do not do exact arithmetic. No calculator is permitted, and a physics or general chemistry answer set is usually spread far enough apart that one significant figure and correct exponents pick the option.
- Flag and move at 90 seconds on a science question you cannot start. The cost of a blank is the same as a wrong answer, and the cost of a stall is two other questions.
- The 30-minute mid-exam break falls between CARS and the second science section, which is where accuracy usually starts to slide. Eat there, not at the 10-minute breaks.
Where the marks are
Introductory biology within Biological and Biochemical Foundations
65% of that section
Questions centre on mechanism and perturbation: what happens to a feedback loop when a hormone is blocked, or what a knockout does to gene expression, rather than definitions.
Introductory psychology within Psychological, Social, and Biological Foundations
65% of that section
The exam asks which named theory or model explains a described behaviour, so precise terminology for learning, memory, perception, and disorders decides the point.
Reasoning Beyond the Text in CARS
40% of the CARS section
You are given new information and asked how it strengthens, weakens, or extends the author's argument. No outside knowledge helps, which is why this skill needs months of daily passages.
General chemistry within Chemical and Physical Foundations
30% of that section
Acid-base and buffer reasoning, equilibrium shifts, and electrochemistry appear repeatedly in biological framing, and all of it has to be done without a calculator.
Introductory sociology within Psychological, Social, and Biological Foundations
30% of that section
Social stratification, institutions, demographic transition, and health disparities come attached to data tables, so reading a figure matters as much as recalling a term.
First-semester biochemistry
25% of Chemical and Physical Foundations and 25% of Biological and Biochemical Foundations
It is the only discipline weighted at 25% in two separate sections. Amino acid properties, enzyme kinetics plots, and pathway regulation carry the load.
Introductory physics within Chemical and Physical Foundations
25% of that section
Fluids, circuits, and optics arrive inside physiology and instrumentation passages, so questions test which relationship applies before they test the algebra.
Organic chemistry within Chemical and Physical Foundations
15% of that section, plus 5% of Biological and Biochemical Foundations
Weighted toward functional group behaviour, stereochemistry, and separation and spectroscopy techniques used in the experimental passages, not toward multi-step synthesis.

If you fail
Wait before retaking
A 24-hour waiting period follows each exam before the MCAT Registration System will let you register again. In practice you also wait 30 to 35 days for the score before deciding, and scheduling closes 10 days before any test date.
Attempt limit
Three attempts in one testing year, four across two consecutive testing years, and seven in a lifetime counting from the April 2015 test dates. Only one appointment may be held at a time. The AAMC will consider an appeal of these limits at its sole discretion and will not consider more than one appeal in a test year.
Retake fee
A retake is a fresh registration at the full price: $355 standard, or $145 under the Fee Assistance Program, plus the $130 international fee where it applies. There is no discounted retake rate.
A voided exam returns no score but still consumes an attempt, so voiding is not a free reset. AMCAS reports every scored attempt to schools rather than only your best, which means a retake is visible alongside the original. Before rebooking, read the section-level scores rather than the total: the four sections are equally weighted, so the cheapest points are usually in whichever section sits furthest below the others.
Exam Domains & Topics
Each of the four sections contributes one 118 to 132 score to the 472 to 528 total, so each carries exactly a quarter of the total score. This section runs 59 questions in 95 minutes and asks you to apply chemistry and physics reasoning to living systems rather than to abstract textbook setups.
Key Topics to Master:
- General chemistry, 30% of the section: acids and bases, buffers, equilibrium, electrochemistry, thermochemistry, solution chemistry
- First-semester biochemistry, 25%: amino acid properties, protein structure, enzyme kinetics and inhibition, bioenergetics
- Introductory physics, 25%: fluids, circuits, optics, thermodynamics, waves and sound, translational motion
- Organic chemistry, 15%: functional group reactivity, stereochemistry, spectroscopy, separation and purification techniques
- Introductory biology, 5%: only the biological framing that the chemistry and physics questions sit inside
- Foundational Concept 5 supplies 60% of the section and Foundational Concept 4 supplies 40%
Fifty-three questions in 90 minutes, all attached to nine passages, and no outside content knowledge is tested. Passages run about 500 to 600 words and split evenly between humanities and social sciences.
Key Topics to Master:
- Reasoning Beyond the Text, 40% of the section: applying the author's argument to a new situation, predicting how new information would change the argument
- Foundations of Comprehension, 30%: main idea, author's tone, the meaning of a word in context, the function of a paragraph
- Reasoning Within the Text, 30%: distinguishing claim from support, spotting internal inconsistency, judging the strength of the author's evidence
- Humanities passages, 50%: ethics, philosophy, literature, art history, studies of culture
- Social sciences passages, 50%: population health, anthropology, economics, political science, sociology
- Vocabulary in context rather than vocabulary recall, since every answer is supported somewhere in the passage
Fifty-nine questions in 95 minutes covering molecular biology up through organ systems. This is the most biology-dense section on the exam, with 65% of its content drawn from introductory biology.
Key Topics to Master:
- Introductory biology, 65%: cell structure, the cell cycle, gene expression, genetics, organ system physiology, immunology, microbiology
- First-semester biochemistry, 25%: metabolic pathways, glycolysis and oxidative phosphorylation regulation, lipid and carbohydrate structure
- General chemistry, 5% and organic chemistry, 5%: the chemical reasoning that supports biological mechanism questions
- Foundational Concept 1 supplies 55% of the section: biomolecules and the transmission of genetic information
- Foundational Concept 3 supplies 25%: organ systems and how they sense and respond to their environment
- Foundational Concept 2 supplies 20%: cells and organisms as highly organized, energy-requiring systems
Fifty-nine questions in 95 minutes drawing on introductory psychology, introductory sociology, and a thin slice of biology. Passages lean heavily on research designs, so reading a results table is as important as recalling a definition.
Key Topics to Master:
- Introductory psychology, 65%: sensation and perception, learning and memory, cognition, emotion, stress, personality theories, psychological disorders
- Introductory sociology, 30%: social stratification, demographics, social institutions, theories of social structure, health disparities
- Introductory biology, 5%: the neural and endocrine basis of behavior
- Foundational Concept 7 supplies 35% of the section: how behavior changes over time through learning, identity, and social influence
- Foundational Concept 6 supplies 25% and Foundational Concept 8 supplies 20%: perception and response to the world, and how people think about themselves and others
- Foundational Concept 9 supplies 15% and Foundational Concept 10 supplies 5%: social structures, and how social inequality affects access and wellbeing
Recommended Study Plan
- 1Sit the free AAMC Sample Test end to end under real conditions: 95, 90, 95, 95 minutes with the real break lengths.
- 2Score it by section and write down which of the four 118 to 132 scores is furthest from your target.
- 3Download the AAMC What's on the MCAT Exam outline and mark each content category as solid, shaky, or never seen.
- 4Register for a test date at least 60 days out: AAMC charges a $55 reschedule fee at 60 or more days before the exam, $110 at 30-59 days and $210 at 10-29 days.
- 5Start the CARS habit that runs the whole plan: two timed passages every day, no exceptions.
- 1Learn all 20 amino acids by structure, three-letter code, one-letter code, and side-chain pKa. This content appears in both C/P and B/B at 25% each.
- 2Work enzyme kinetics until you can read a Lineweaver-Burk plot and name the inhibition type in under 20 seconds.
- 3Cover glycolysis, the citric acid cycle, and oxidative phosphorylation with the regulated steps flagged.
- 4Do the AAMC Biology Question Pack Volume 1 sections on metabolism and review every explanation, including the ones you got right.
- 5Keep the two daily CARS passages going and log the question type of each miss.
- 1Cover acids, bases, buffers, and titration curves. General chemistry is 30% of the C/P section, the biggest single discipline share anywhere on the exam.
- 2Drill equilibrium, Ksp, and Le Chatelier reasoning with orders-of-magnitude estimation rather than a calculator, since no calculator is permitted.
- 3Cover electrochemistry, thermochemistry, and gas laws.
- 4Do a timed 59-question C/P block from a third-party bank and check whether your pace clears 95 minutes.
- 5Continue daily CARS and add one full timed 53-question CARS section at the end of the week.
- 1Cover fluids, circuits, optics, thermodynamics, and waves. Introductory physics is 25% of C/P.
- 2Practise estimation: rounding to one significant figure and tracking exponents is faster than exact arithmetic on the noteboard.
- 3Build a formula sheet from memory each morning, then check it. Recall beats rereading.
- 4Work through the AAMC Physics Question Pack and mark every question you solved by formula-hunting rather than reasoning.
- 5Daily CARS continues; start categorising misses as Comprehension, Within the Text, or Beyond the Text.
- 1Cover functional group reactivity, stereochemistry, and the reactions that appear in biological contexts. Organic chemistry is 15% of C/P and 5% of B/B.
- 2Learn separation and purification techniques cold: chromatography, electrophoresis, distillation, extraction. These show up in experimental passages.
- 3Learn IR and NMR interpretation at the level of identifying a functional group from a peak.
- 4Do the AAMC Chemistry Question Pack and record which misses were content gaps versus passage misreads.
- 5Take one timed CARS section and compare its score with week 3's.
- 1Cover DNA replication, transcription, translation, and gene regulation. Introductory biology is 65% of the B/B section.
- 2Cover the cell cycle, mitosis, meiosis, and classical genetics including pedigree and Hardy-Weinberg problems.
- 3Cover the biotechnology toolkit: PCR, gel electrophoresis, Southern and Western blotting, CRISPR, knockouts. Experimental passages assume it.
- 4Do a timed 59-question B/B block and review every explanation.
- 5Daily CARS continues.
- 1Cover cardiovascular, respiratory, renal, endocrine, nervous, digestive, immune, and reproductive physiology, which is Foundational Concept 3 at 25% of B/B.
- 2For each system, write the feedback loop rather than a list of parts. MCAT questions ask what happens when a loop is perturbed.
- 3Cover immunology in detail: innate versus adaptive, B and T cell function, antibody structure.
- 4Do the AAMC Section Bank Volume 1 biology set, which is harder than the practice exams and exposes reasoning gaps.
- 5Daily CARS continues.
- 1Cover sensation and perception, learning theories, memory models, cognition, and language. Introductory psychology is 65% of the P/S section.
- 2Cover emotion, motivation, stress, personality theories, and the major psychological disorders with their diagnostic features.
- 3Build a flashcard deck of named theories and named researchers. P/S rewards precise terminology more than any other section.
- 4Do a timed 59-question P/S block and review the research-design questions separately.
- 5Daily CARS continues.
- 1Cover social stratification, social institutions, demographic transition, and theories of social structure. Introductory sociology is 30% of P/S.
- 2Cover health disparities and social determinants of health, which map to Foundational Concept 10.
- 3Drill research design and statistics: independent and dependent variables, confounders, correlation versus causation, reading error bars.
- 4Do the AAMC Section Bank Volume 2 psychology and sociology set.
- 5Daily CARS continues; take one timed CARS section.
- 1Take AAMC Full Length Practice Exam One at the same start time as your real test date, with the real 10-10-30 break pattern.
- 2Spend two full days reviewing it. Write one sentence per miss naming the cause: content gap, misread, careless, or timing.
- 3Rank your four section scores and give the weakest section 40% of the coming week.
- 4Rebuild flashcards only from the causes labelled content gap.
- 5Daily CARS continues.
- 1Reteach the two weakest content categories out loud without notes, then check yourself against the AAMC outline.
- 2Redo every missed question from your full-length and question packs without looking at the explanations.
- 3Take AAMC Full Length Practice Exam Two and compare section by section with Exam One.
- 4Practise the 30-minute mid-exam break as a routine: same food, same movement, same timing.
- 5Daily CARS continues.
- 1Take two AAMC full-length exams this week with a full review day after each.
- 2Rebuild your endurance for the 7-hour 30-minute seated day by never splitting a practice exam across two sittings.
- 3Work the AAMC Official Guide questions for the sections still lagging.
- 4Confirm your ID meets AAMC rules: government issued, unexpired, photo, in English, name matching your registration exactly.
- 5Daily CARS continues.
- 1Take your last AAMC full-length no later than five days before test day.
- 2Review it the same day and the next, then stop taking full-lengths.
- 3Run one last pass over amino acids, hormone origins and targets, and named psychology theories, which are the highest-density recall items.
- 4Confirm your test centre location, arrival plan, and what you can access during breaks.
- 5Reduce CARS to one passage a day to keep the habit without draining focus.
- 1Do light content review only, in blocks no longer than 90 minutes.
- 2Sleep on your test-day schedule for at least four nights, since the exam starts early and runs seven and a half hours.
- 3Pack the night before: valid physical ID, no digital wallet substitute, food and drink for the mid-exam break.
- 4Decide in advance that you will not void unless something genuinely disqualifying happened, because you get 3 minutes to choose.
- 5Sit the exam.

Common Mistakes to Avoid
Treating the four sections as unequal because one has fewer questions
CARS has 53 questions to the science sections' 59, but every section contributes one 118 to 132 score to the 472 to 528 total. A CARS point costs exactly what a biochemistry point costs. Allocate study time by your section score gap, not by question count.
Leaving questions blank to avoid a guessing penalty
The AAMC states plainly that wrong answers are scored exactly the same as unanswered questions. There is no penalty. Every blank is a guaranteed zero where a guess is a one-in-four chance.
Saving all AAMC material for the last two weeks
AAMC items behave differently from third-party items, and the Section Bank in particular exposes reasoning gaps that take weeks to close. Start official material by week 5 so there is time to act on what it reveals.
Underweighting psychology and sociology because the content feels easy to read
Introductory psychology alone is 65% of the P/S section, and P/S carries a full quarter of your total score. The section punishes imprecise terminology: it asks which named theory applies, not whether you understood the passage.
Practising physics and general chemistry with a calculator
No calculator is permitted. You get a noteboard booklet and a fine-point marker. If your arithmetic is trained on a calculator, the C/P section will cost you time you cannot recover. Practise rounding to one significant figure and tracking exponents.
Rescheduling inside the expensive window
Rescheduling costs $55 at 60 or more days out, $110 at 30 to 59 days, and $210 at 10 to 29 days. Below 10 days no change is allowed at all. Book early enough to stay in the $55 band.
Registering under a name that does not match your ID
The first and last names on your ID must exactly match your MCAT registration, in the same order. A mismatch means you are turned away at the door and lose the sitting. Fix the registration, not the ID.
Voiding the exam out of panic during the 3-minute void window
You get 3 minutes at the end to void. A voided exam still counts toward your three-per-year and seven-lifetime limits and returns no score at all. Candidates routinely feel worst about sections they scored well on, so decide your void criteria before test day.
Reviewing only the questions you got wrong
A correct answer reached by elimination or luck is a future miss. Mark confidence as you go and review every low-confidence question, including the correct ones.
Practising full-lengths in two sittings
Total seated time is about 7 hours 30 minutes. Stamina failure in the fourth section is a common score leak, and it is only trainable by sitting the whole thing in one block with the real 10, 30, and 10 minute break structure.
Exam Day Tips
- 1
Bring an original, physical, unexpired, government-issued photo ID in English whose first and last names match your registration exactly. Digital IDs, school IDs, employee IDs, birth certificates, and social security cards are all refused.
- 2
A US state driver's license or a passport is the safest choice. The AAMC also lists passport cards, permanent resident cards, Employment Authorization Documents, consular ID cards, Ontario and British Columbia health cards, and Canadian aviation cards.
- 3
Expect the check-in to include a digital palm scan and a test-day photograph in addition to the ID check. Build that into your arrival timing.
- 4
Do not bring a calculator. You get a noteboard booklet and a fine-point marker, and that is the whole toolkit for arithmetic across 230 questions.
- 5
Use the 10-minute optional tutorial only if you have never seen the interface. If you have taken AAMC full-lengths, skip it and start the first section on a fresh brain.
- 6
Plan the 30-minute mid-exam break as a meal, not a snack. It sits between CARS and Biological and Biochemical Foundations, the point where most candidates start losing accuracy.
- 7
Know what you may access during breaks before you get there, and store everything else in the secured locker at check-in.
- 8
Answer every question. A blank scores the same as a wrong answer, so there is never a reason to leave one empty when time is running out.
- 9
The void question appears for 3 minutes after the last section. A void means no score and still burns an attempt against your seven-lifetime cap.
- 10
Expect your score 30 to 35 days later. No unofficial result appears on the day, so there is nothing to check that evening.
Career Paths & Salary Ranges
MD programme matriculant
The direct outcome of an MCAT score. The 2025 cycle saw 54,699 applicants and 23,440 matriculants, with matriculants averaging 512.1 on the MCAT and 3.81 GPA.
No salary. US MD tuition and fees, plus living costs, run into six figures across four years
Resident physician
The paid training years after the MD or DO. Residency length runs three years for family medicine up to seven for neurosurgery, and salary rises modestly by post-graduate year.
PGY-1 stipends published by individual teaching hospitals typically fall in the $60,000 to $75,000 range
Attending physician, primary care
Board-certified practice in family medicine, general internal medicine, or general paediatrics after residency. Pay varies more by geography and employment model than by any other factor.
Compensation surveys published by MGMA and by physician recruiters place family medicine and general internal medicine well below procedural specialties
Attending physician, procedural specialty
Fields such as orthopaedic surgery, cardiology, and anaesthesiology. These require the longest training pipelines and the most competitive residency matches.
Surgical and interventional specialties sit at the top of published physician compensation surveys, well above primary care
Physician-scientist (MD-PhD)
Dual-degree training combining clinical medicine with a research doctorate. Programmes are smaller and more competitive than MD admissions, and the MCAT remains a required component.
MD-PhD programmes are typically tuition-waived with an NIH-benchmarked stipend; NIH publishes its NRSA predoctoral stipend levels annually
Osteopathic physician (DO)
DO programmes accept the MCAT and admit with score distributions that differ from MD programmes. AACOMAS reports admissions data separately from AAMC.
DO and MD graduates enter the same ACGME residency match and the same attending salary bands by specialty
Prerequisites & Requirements
- No coursework prerequisite. The AAMC states you are eligible to take the MCAT if you are planning to apply to a health professions school, which includes MD-granting programmes among others.
- An AAMC ID with an associated username and password, created before you can register in the MCAT Registration System.
- A valid, unexpired, government-issued, physical photo ID in English whose first and last names match your registration exactly.
- The exam content assumes one year of general chemistry, one year of organic chemistry, one year of physics, one year of biology, one semester of biochemistry, and introductory psychology and sociology. These are content assumptions, not registration gates.
- Individual medical schools set their own course prerequisites for admission, and those are separate from MCAT eligibility. Check each school's entry in the Medical School Admission Requirements database.
- Accommodations require a separate application through the AAMC's centralised MCAT and PREview accommodations system, submitted and approved before you schedule.
Frequently Asked Questions
How much does the MCAT cost?
Standard registration is $355. The AAMC Fee Assistance Program reduces it to $145, a $210 saving. Examinees testing outside the United States, Canada, or US territories pay an additional $130 international fee, which the AAMC does not refund if you cancel. The registration fee covers both the exam and the distribution of your scores.
What happens if I need to reschedule or cancel?
Rescheduling costs $55 at 60 or more days before your exam, $110 at 30 to 59 days, and $210 at 10 to 29 days. Fee Assistance Program examinees pay $25, $45, and $85 for the same windows. Cancelling returns $175 at 30 or more days out and nothing at 10 to 29 days; the Fee Assistance refund is $75 and $0. No changes of any kind are allowed inside 10 days.
How many times can I take the MCAT?
Three times in a single testing year, four times across two consecutive testing years, and seven times in a lifetime counting from the April 2015 administrations. You may hold only one appointment at a time, and there is a 24-hour waiting period after you finish an exam before you can register for another. The AAMC will consider an appeal of these limits but will not consider more than one appeal per test year.
Is there a waiting period between MCAT attempts?
There is a 24-hour waiting period after completing an exam before the MCAT Registration System will let you register again. Beyond that, the practical limit is the attempt cap of three per testing year rather than a fixed interval, plus the 30 to 35 days you should wait to see your score before deciding.
What is a passing MCAT score?
There is no passing score. The MCAT reports a scaled total from 472 to 528, built from four section scores of 118 to 132. Schools set their own expectations. For context, the AAMC reported a 2025 applicant mean of 506.3 and a matriculant mean of 512.1.
How does the MCAT score scale work?
Each section converts your number of correct answers to a scaled score from 118 to 132 through equating, which adjusts for small difficulty differences between forms. The four section scores add to a total between 472 and 528. The AAMC states the exam is not curved: the conversion is tied to the specific questions on your form, not to how other people did that day.
Do wrong answers cost me marks?
No. The AAMC states that wrong answers are scored exactly the same as unanswered questions and do not affect your score. Guess on everything you cannot solve, and never leave a question blank when time runs out.
When do MCAT results arrive?
Thirty to thirty-five days after your test date. There is no unofficial score on test day. The AAMC uses that window to scale and equate the form and to review any reported concerns about questions or testing conditions.
What percentile is my score?
The percentile table in effect from May 1, 2026 to April 30, 2027 is based on 305,494 results from the 2023, 2024, and 2025 testing years, with a mean of 500.6 and a standard deviation of 11.2. On that table, 500 is the 48th percentile, 508 the 74th, 512 the 84th, 515 the 91st, 520 the 97th, and 522 the 99th. Percentiles refresh every May 1.
Can I use a calculator?
No. The AAMC issues a noteboard booklet and a fine-point marker for all scratch work, and that is the only calculation aid on the exam. Physics and general chemistry questions are built so that estimation and unit reasoning get you to the right option without exact arithmetic.
What ID do I need on test day?
An original, physical, unexpired, government-issued photo ID printed in English, with first and last names exactly matching your MCAT registration in the same order. Driver's licences and passports are the most common accepted forms. Digital IDs, photocopies, school or employee IDs, birth certificates, and social security cards are refused, and without a valid ID you will not be allowed to test.
What happens at check-in?
You sign in, present your ID, have your palms digitally scanned, and have a test-day photograph taken. Personal belongings go into a secured locker. The palm scan is repeated when you leave and re-enter the testing room around breaks.
How do the breaks work?
You get three optional breaks: 10 minutes after the Chemical and Physical Foundations section, 30 minutes after CARS, and 10 minutes after Biological and Biochemical Foundations. They are optional, but taking a break that runs longer than scheduled eats into your next section, so treat the clock as fixed.
Can I get accommodations?
Yes. The AAMC runs a single centralised accommodations application covering both the MCAT and the AAMC PREview exam. Approved accommodations can include extended testing time and extended breaks. Apply and get approval before scheduling, because approval is not retroactive to an already-booked appointment.
What is the void option and should I use it?
After the last section you get 3 minutes to decide whether to void. A void means no score is produced and no score is reported to schools, but the sitting still counts against your three-per-year and seven-lifetime attempt limits. Decide your criteria before test day, because feeling bad about a section is a poor predictor of how it scored.
How long is an MCAT score valid?
The AAMC does not expire scores, but each medical school sets how old a score it will accept, commonly two to three years. Check the school's entry in the Medical School Admission Requirements database, because a score that one school accepts may be too old for another in the same cycle.
Do schools see all my MCAT attempts?
AMCAS reports all your scored MCAT results, so schools see the full history rather than only your best. Voided exams produce no score. Individual schools differ in whether they consider your highest total, your most recent, or a composite view.
Is the MCAT harder than the DAT?
They test differently. The MCAT runs 230 questions across 6 hours 15 minutes of testing and adds a full 53-question critical reading section with no content to memorise, plus a psychology and sociology section. The DAT, run by the American Dental Association, is shorter and includes a perceptual ability test that the MCAT has no equivalent of. Candidates commonly find MCAT CARS the hardest single section on either exam because it cannot be closed by content review.
How does the MCAT compare with the AAMC PREview exam?
They are separate exams with separate rules. PREview assesses professional readiness rather than science content, allows two attempts per administration year with a lifetime limit of four, and is required only by participating schools. The MCAT is the science and reasoning exam required broadly, with three attempts per testing year and seven in a lifetime.
How many hours should I study?
There is no AAMC-published figure. What the exam structure demands is measurable: 230 questions across four sections, a content outline that spans two semesters each of chemistry, physics and biology plus biochemistry, psychology and sociology, and a 7 hour 30 minute seated day that has to be trained for. Most candidates build a plan of at least three months and take every AAMC full-length exam before test day.
Success Stories
“I studied for 5 months while finishing my degree. AAMC materials are everything - don't try to save money here. UWorld was great for practice. Daily CARS practice for 4 months made that section manageable.”
Rachel Kim
Johns Hopkins Med School
“I took the MCAT twice - 509 then 517. The first time I relied too heavily on content review. Second attempt focused on practice problems and understanding my mistakes.”
David Nguyen
UCLA Medical School
“Khan Academy for free content review, UWorld for practice, all AAMC materials. That's the winning combination. Don't neglect psych/soc - it's a third of the test!”
