Pass Rate
Understand the new system before studying anything
Week 15-6 hours this week
- Read the ECOEMS convocatoria on miderechomilugar.gob.mx in full, since the process replaced COMIPEMS and older advice no longer applies
- Obtain your Llave MX at llave.gob.mx, because registration is impossible without it
- Decide your modality: direct access without exam, exam for IPN and UNAM, or mixed
- Check that you will hold a Certificado de Educacion Secundaria, since assignment is only made to candidates who have one
- If you are aiming at IPN or UNAM, confirm you will reach the minimum secundaria average of 7.0
Option list strategy
Week 25-6 hours this week
- Read the catalogo de opciones educativas published on miderechomilugar.gob.mx from the start of registration
- In the no-exam modality, choose between five and ten options; in the mixed modality you may register up to 20
- Order your list honestly by preference, because the SEP states that this order is the assignment criterion
- Use the distance data: the SEP reports 80 percent of new entrants now study within 7 kilometres of home, so nearby options are realistic ones
- Have a parent or guardian read the list with you, since the registration of a minor is a shared responsibility under the instructivo
Diagnostic and baseline
Week 38-10 hours this week
- Sit a full 128-question practice exam in one three-hour block to find your starting point
- Score by subject area so you know where your correct answers actually come from
- Note where you ran out of time rather than out of knowledge, which is a different problem
- Download the official guide from the exam portal once your payment is processed, since it is included in the fee
- Register for Prueb@te UNAM Bachillerato at pruebate.bach.unam.mx, noting that its cost is not included in the exam payment
Habilidad verbal
Week 48-10 hours this week
- Work analogies daily until you can name the relationship type before looking at the options
- Read one non-fiction article a day and write the main idea in a single sentence
- Build a vocabulary list from words you meet in practice items rather than from a generic list
- Practise sentence completion by predicting the missing word before reading the choices
- Time yourself: verbal items should take well under the overall average of 1 minute 24 seconds each
Habilidad matematica
Week 58-10 hours this week
- Drill numeric and figural series until you recognise the common patterns on sight
- Practise proportional reasoning and rule of three problems without a calculator, since calculators are prohibited
- Work word problems by translating each sentence into an equation before solving
- Practise reading tables and charts and answering only what the question asked
- Do mental arithmetic daily so paper is used for working rather than for basic operations
Matematicas
Week 610-12 hours this week
- Review operations with fractions, decimals and negative numbers until they are automatic
- Solve linear equations and systems of two equations by both substitution and elimination
- Factorise and solve quadratics, and know when the quadratic formula is faster than factorising
- Revise perimeter, area and volume formulas and practise applying them to composite figures
- Work Pythagoras and similarity problems, then basic trigonometric ratios
Espanol
Week 78-10 hours this week
- Learn the accentuation rules systematically: agudas, graves, esdrujulas and sobresdrujulas, then diacritical accents
- Drill the commonly confused letter pairs until spelling items are automatic
- Revise punctuation rules with real sentences rather than isolated rules
- Revise verb tenses and subject-verb agreement
- Learn literary genres and the main figures of speech with one clear example each
Biologia
Week 88-10 hours this week
- Draw the cell and label it from memory, since biology is the most visual area of the exam
- Draw and label the human body systems, one per day
- Work Mendelian genetics problems with Punnett squares
- Diagram energy flow through an ecosystem and the main biogeochemical cycles
- Revise health, nutrition and reproduction, which are standard secundaria content
Fisica y quimica
Week 910-12 hours this week
- Build a formula sheet for motion, force, work, energy and power, then rebuild it from memory
- Practise unit conversion deliberately, because units are the most frequent source of wrong answers in physics items
- Practise reading the periodic table rather than memorising elements: groups, periods, atomic number and mass
- Balance chemical equations until the method is mechanical
- Revise acids and bases, mixtures and separation methods
Historia y geografia
Week 108-10 hours this week
- Build one timeline for world history and one for Mexican history, and study in chronological order
- Revise Mexican history in sequence, since each period explains the next
- Study geography on maps rather than from lists of names
- Revise climate, natural regions, population and economic activity
- Use spaced repetition for dates: short daily reviews beat one long session
Formacion civica y etica, plus technical preparation
Week 118-10 hours this week
- Revise rights and obligations, the constitution, division of powers and forms of government
- Revise democracy, participation, human rights and discrimination
- Download and install the LockDown Browser during the published window, on the exact computer you will use
- Uninstall any screen recording software, because the secure browser detects it and will not run
- Test the webcam and microphone with the practice check, and repeat it up to 72 hours before the exam
Simulator and full rehearsals
Week 1210-12 hours this week
- Sit the official simulator at the exact date and time on your Cita de examen, since there is no rescheduling and it is compulsory
- Use the simulator to fix lighting, camera angle and background, because the AI monitoring flags images of people in the background
- Sit two more full 128-question rehearsals in three-hour blocks
- Rehearse with only the permitted materials: two blank sheets, pencil, eraser and sharpener
- Confirm your exam date and time from Documento B and tell everyone in the house
