Pass Rate
10-12 hours this week
- Sit a full-length mock under exam conditions: 120 minutes, three 40-minute locked sections, no breaks
- Record raw score, accuracy and attempts separately for VARC, DILR and QA
- Download the CAT 2026 Information Bulletin from iimcat.ac.in and confirm your eligibility on the 50 percent or 45 percent rule
- Read the IIM Ahmedabad and IIM Calcutta 2026-28 shortlisting criteria so you know the sectional percentiles you are aiming at
- Register on iimcat.ac.in before the 5:00 p.m. September 15, 2026 deadline if you have not already
14-16 hours per week this week
- Rebuild arithmetic from percentages through ratio, averages, mixtures and time-speed-distance using Arun Sharma's How to Prepare for Quantitative Aptitude for CAT
- Memorize squares to 30, cubes to 20, reciprocals to 1/20 and common fraction-to-percentage conversions
- Read one long-form non-fiction article a day from Aeon, The Economist or 3 Quarks Daily and write a 40-word summary of each
- Solve 20 arithmetic questions daily with a 90-second cap per question
- Work the official CAT mock on iimcat.ac.in once to learn the interface, the on-screen calculator and the section timer
16-18 hours per week this week
- Cover linear and quadratic equations, inequalities, functions and logarithms
- Drill remainders, factors, divisibility and cyclicity from Nishit Sinha's Pearson Guide to Quantitative Aptitude
- Solve four DILR sets a day from past CAT papers, timing each set separately and noting which ones you should have skipped
- Build a personal taxonomy of DILR sets: pure data, caselet, arrangement, distribution, games, network
- Start a running error log with three columns: question, why it went wrong, what rule prevents the repeat
16-18 hours per week this week
- Cover triangles, circles, quadrilaterals, coordinate geometry and mensuration, and memorize the standard formulas cold
- Work permutations, combinations, probability and set theory with 30 questions per topic
- Attack VARC by question type: 20 para-summary questions, then 20 odd-sentence-out, then 20 para-jumbles, in blocks
- For every reading comprehension passage, mark the option you eliminated last and write one line on why the correct answer beat it
- Solve two full DILR sections from past papers each week under a 40-minute lock
18-20 hours per week this week
- Work through released CAT papers from the last eight years, one section at a time under the 40-minute lock
- Rank your DILR set-selection decisions after each attempt: which set you should have opened first and which you should have left
- Rebuild any QA topic where accuracy is below 70 percent rather than adding new topics
- Practise 10 type-in-the-answer questions a day, since they carry no negative marking and are pure upside
- Test the on-screen calculator against mental arithmetic on 20 calculation-heavy questions and record which was faster
20-22 hours per week this week
- Sit two full-length mocks per week at 8:30 a.m., 12:30 p.m. and 4:30 p.m. slot times to match the three CAT sessions
- Spend three hours analysing every mock, which is more time than the mock itself takes
- Fix a section-entry rule for each section and stop changing it: for example, read all DILR sets in minutes 0 to 4, commit to three, review at minute 30
- Track percentile movement rather than raw score, since scaled scores and percentiles are what institutes read
- Convert your error log into a one-page list of recurring mistakes and read it before every mock
8-10 hours this week
- Cut to one mock, then stop taking full mocks four days before the test
- Download the admit card, which is available from November 4, 2026, and print it
- Affix a copy of the same photograph you uploaded at registration onto the admit card, as the CAT registration guide requires
- Confirm your allotted centre address and do a travel dry run if the city is unfamiliar, since no centre change is permitted once allotted
- Revise formula sheets and the error log only, and sleep on the same schedule as your test session
Ongoing this week
- Apply separately to each IIM through its own portal, because CAT registration alone does not apply you to any programme
- Prepare for the Writing Ability Test or Analytical Writing Test and personal interview from December, since IIM Ahmedabad publishes shortlists tentatively in the second week of January
- Rehearse for a personal interview weighted at 48 of 100 final-selection points at IIM Calcutta and a 0.50 multiplication factor at IIM Ahmedabad
- Assemble work-experience proof: employer letters on letterhead with start date, end date, designation and payslips, which IIM Calcutta requires
- Track that a CAT 2026 score expires on December 31, 2027 and plan any repeat attempt accordingly
