CAT Last Month Revision Plan: Consolidate, Calibrate, Cut
Four weeks out, the syllabus is whatever it is. Topics you have not learned by now will not become reliable in time, and the hours spent trying come out of the two things that still move: consolidating what you already know, and calibrating how you use it under a clock.
So the final month has three jobs. Consolidate. Calibrate. Cut. Most candidates attempt only the first, run out of time for the second, and never consider the third at all.
The revision hierarchy
Not all revision is worth the same, and the ranking is close to the reverse of what candidates reach for when they are anxious.
| Rank | What you revise | Why it sits here |
|---|---|---|
| 1 | Your error log | Targeted at mistakes you have actually made, not at topics in general. Nothing else comes close |
| 2 | Mock analysis from the last six weeks | Shows patterns the log entries individually do not — a recurring selection error, a section you consistently rush |
| 3 | A one-page formula sheet you wrote yourself | Writing it is most of the value. A downloaded sheet is somebody else's compression of somebody else's understanding |
| 4 | Topic notes for your two weakest areas | Only the two. Revising everything means revising nothing properly |
| 5 | Textbook chapters | Too slow to be worth it now. If a topic needs the textbook in week three, it is a cut candidate |
The gap between rank one and rank five is enormous, and it is worth being blunt about why. Reading a chapter feels productive because it covers ground. Re-solving four questions you got wrong in September feels slow and unglamorous, and it is worth several times more, because it is aimed at a demonstrated failure rather than at a general subject.
Four weeks, four jobs
Close what is nearly closed
Topics sitting at seventy per cent get finished this week. Topics sitting at twenty per cent get cut, formally, in writing. Three mocks, each fully reviewed. This is the last week new material is allowed anywhere near your desk.
Sectionals at the weakest area
Four sectionals aimed where the mocks say you are losing marks, plus two full papers. Write the one-page formula sheet this week — by hand, from memory first and notes second.
Full mocks and error-log passes
Three mocks at your slot timing. Between them, the error log and nothing else. No topic notes. No new sources. Start shifting your sleep toward exam morning.
Taper
Two mocks early, then logistics, then nothing at all. The final week runs on its own rules and almost none of them involve studying.
Is three mocks a week too many?
It is if you are not reviewing them. A mock plus a proper review is about 165 minutes, so three a week is roughly eight hours before you have studied anything. If that does not fit, take two and review both — a reviewed mock is worth several unreviewed ones, and candidates who cut review to fit more mocks in have the trade exactly backwards.
Cutting, which nobody wants to do
This is the part of the month that gets skipped, and skipping it is expensive. A topic you have postponed for four months is not going to be learned in the fifth, and every hour you spend pretending otherwise is an hour taken from something that would have worked.
Cut formally. Write the list down. A topic you have vaguely decided to abandon still occupies attention, still generates guilt, and still pulls you back mid-revision — whereas a topic you have written on a page headed "not this year" stops doing all three.
- Cut anything below about thirty per cent accuracy that would need the textbook to fix.
- Cut low-frequency topics you find hard. The combination is what matters — a hard topic that appears often is worth keeping.
- Do not cut anything in your weakest section wholesale. Sectional minimums are screened separately, so a section cannot be abandoned the way a topic can.
- Write the list on one page and put it somewhere you will see it, so the decision stays made.
- Revisit the list once, in week two. Not to add topics back — to confirm you are not still quietly working on them.
CAT Mock Test — the month runs on this data
Which topics to cut and which section to drill are decisions the mock report makes for you. Guessing at them wastes the month.
Calibration, the job nobody schedules
Consolidation is about knowing things. Calibration is about knowing what you can do with them under forty minutes of pressure, and it is a separate skill that improves separately.
Three things to calibrate deliberately this month.
How long does a question actually take you?
Most candidates estimate two minutes and take three and a half. Check it against the mock report rather than your impression, because every pacing decision you make rests on this number and a wrong one propagates through all of them.
What does your accuracy do when you speed up?
Take one mock deliberately fast and compare. Some candidates hold accuracy and should therefore attempt more; others collapse and should attempt fewer. You cannot know which you are without testing it, and it is the single most useful experiment available in the final month.
Can you tell a hard question from an easy one before solving it?
This is what selection actually is. After each mock, rank the questions you skipped by how long they would have taken — if the ones you skipped turn out to have been the fast ones, your problem is selection rather than speed, and that is a very different fix.
What should you be cutting?
The cut list should come from accuracy data, not from how a topic feels. Section and topic-level results make the decision for you.
- Accuracy by section
- Time per question
- Sectional percentiles
Questions candidates actually ask
How should I revise in the last month before CAT?
By hierarchy rather than by syllabus. Your error log comes first because it targets mistakes you have actually made; then mock analysis from the last six weeks, which shows patterns individual log entries do not; then a one-page formula sheet you write yourself; then topic notes for your two weakest areas only. Textbook chapters come last and are usually not worth the hours at this stage.
Should I learn new topics in the last month?
Only in week four, and only topics already sitting around seventy per cent. Anything at twenty per cent should be cut formally rather than carried. A topic postponed for four months will not become reliable in the fifth, and the hours spent attempting it come out of consolidation and calibration — both of which still move at this stage, which is exactly what new learning no longer does.
How many mocks should I take in the final month?
Roughly ten across four weeks, tapering toward the end — three in week four, two plus four sectionals in week three, three in week two and two early in the final week. The constraint is review rather than mocks. A mock plus proper review runs about 165 minutes, so if three a week does not fit, take two and review both. A reviewed mock is worth several unreviewed ones.
What does it mean to cut a topic?
Deciding formally, in writing, that a topic is not part of this attempt. The writing matters more than it sounds — a topic you have vaguely abandoned still occupies attention, generates guilt and pulls you back mid-revision, whereas one written on a page headed "not this year" stops doing all three. Cut low-frequency topics you find hard, and anything below about thirty per cent accuracy that would need the textbook to fix.
Can I cut a whole section?
No. Almost every institute screens sectional percentiles separately from the overall figure, so a weak section fails filters that a balanced profile clears — which means a section cannot be abandoned the way an individual topic can. You can cut topics within your weakest section, and you should, but the section itself has to keep receiving time right through the month.
What is calibration and why does it matter?
Knowing what you can actually do under forty minutes of pressure, as distinct from knowing the material. Three things are worth calibrating deliberately: how long a question really takes you against the report rather than your impression, what happens to your accuracy when you deliberately speed up, and whether you can tell a hard question from an easy one before solving it. That last one is what selection is, and it is fixable separately from speed.
Should I switch test series in the last month?
No. A new platform brings unfamiliar difficulty calibration and an interface you have not practised on, precisely when comparability with your own earlier scores matters most. Whatever the flaws of the series you have been using, its scores are interpretable to you because you have a history with them — and a fresh percentile from an unfamiliar platform in week two tells you very little except how unsettling it feels.
