- No official data says how many CAT mocks are enough. Published counts run from under 20 to 60 and come from sellers or one company's own figures.
- A better question is how many mocks you can review properly. A full mock costs about 3.5 hours: 2 for the test and 1.5 for the review.
- A worked plan: one diagnostic, then one full mock a week, then two a week in the last four weeks. The 90-day plan on this site totals 13 full mocks and 12 sectionals.
- Never start a new mock while the last one is unreviewed, and take no mock in the last two days.
- Judge a mock by whether your error log and section metrics improve, not by one score.
How many CAT mocks you need depends on how many you can review properly, and there is no official number. A mock measures you; the review is what trains you. A plan with 13 reviewed full mocks can beat one with 40 mocks that were never analysed.
This post works out a mock count from your available hours, explains why the mock counts you see online vary so much, and gives counts by phase and an 8-week calendar. CAT 2026 is on 29 November 2026, 23 days after 6 November, so a short note for that cohort is included.
How many CAT mocks do you need? Start from hours, not from a count
A full CAT mock runs 120 minutes, and a good review takes about 90 minutes. That is 3.5 hours per mock. Your count follows from the hours you can give to mocks each week.
- One full mock plus its review = 2 + 1.5 = 3.5 hours.
- 7 / 3.5 = 2.
Answer: Two full mocks a week, spaced at least two days apart. With 3.5 hours you can do one.
If you cannot review a mock within 24 hours, you do not yet have time for another one.
Why the mock counts you see online vary so much
Counts you will see online run from under twenty to sixty or more. None of them is an official figure, and none comes with data we can check.
Some describe people who already did well, which cannot show that taking that many mocks caused the result. Others come from sellers who gain when you buy more. Anecdotes also vary: some candidates improve within a handful of mocks, others stall through dozens. Use your own review time to set the number.
Mocks per phase: baseline, build, simulate
Count by purpose. The 90-day study plan on this site gives a worked example.
| Phase | Weeks of the 90-day plan | Full mocks | Sectionals | Purpose |
|---|---|---|---|---|
| Baseline | 1 to 4 | 1 (diagnostic in week 4) | 1 a week | Find the gap. Do not judge the score |
| Build | 5 to 8 | 1 a week | 1 a week | Practise timing while topics are still being covered |
| Simulate | 9 to 12 | 2 a week | 1 a week | Rehearse the real 120 minutes |
| Taper | 13 (6 days) | None | None | Revise the error log only |
That adds up to 13 full mocks and 12 sectionals in 90 days. With a longer start, take one diagnostic early, one sectional every two weeks, and a full mock a month until the last 90 days begin.
How much review time each mock needs
| Minutes | Step |
|---|---|
| 10 | Scorecard per section: attempted, correct, wrong, skipped, minutes |
| 30 | Re-solve every wrong answer and label the error type |
| 15 | Skipped but solvable: find out why you skipped |
| 15 | Right but slow: find a faster method |
| 10 | Re-solve the three costliest questions cold |
| 10 | Update the error log and set three actions |
That is 90 minutes, as set out in the mock analysis guide. Two full mocks a week then take 7 hours with reviews. Against the 34-hour student week and 27-hour working week of the plan's mock-heavy phase, that is about 21% and about 26% of your time.
Sectional tests versus full mocks
- Sectional (40 minutes): practise one section, review it quickly, and use it on the section you are weakest in.
- Full mock (120 minutes): practise stamina, section order and timing with no switching between sections.
- Set your mock to the real rules: three sections of exactly 40 minutes, +3 for a correct answer, -1 for a wrong MCQ and no negative marks for non-MCQs.
The free CAT Compass mock is shorter than the real paper and lets you switch sections. Use it as a diagnostic, and take full-length mocks for the rules above.
How to tell that a mock is helping
One score tells you little. Watch these instead:
- Logged questions are right when you retest them after three and ten days.
- One metric per section moves across three mocks, such as accuracy above 75%, no question over 2.5 minutes, or two DILR sets solved.
- The same error type shrinks in your log from one mock to the next.
Treat percentiles as a band. If your last four mocks give 88, 91, 90 and 94, the average is 90.75, so plan around about 91 and not around 94. A mock percentile also compares you with that platform's users, so track your own trend.
Mock fatigue and when to pause
Pause when you have more than one unreviewed mock, when scores stay flat across three mocks while your reviews are thin, or when you notice you are skimming the solutions. Spend the next few days clearing the review backlog and drilling the error-log topics.
A sample 8-week mock calendar
This follows weeks 5 to 12 of the 90-day plan. Count back from the official exam date for the cycle you are targeting.
| Weeks | Full mocks | Sectional | Review |
|---|---|---|---|
| 1 to 4 | 1, at the weekend | 1, on your weakest section | Next day, 90 minutes |
| 5 to 8 | 2, at least two days apart | 1, on your weakest section | Within 24 hours of each mock |
| After week 8 | None | None | Error log only |
For CAT 2026, the same plan puts 10 to 16 November and 17 to 23 November in the two-mock phase and 24 to 29 November in the no-mock week. The official result is likely in the first week of January 2027.
