Your IIM Call Is Decided After CAT: 6 Mistakes in the Last 6 Weeks

CAT 2026 is about six weeks away. Most aspirants spend these weeks the wrong way: more mocks, less analysis, panic changes and no plan for what comes after the exam. Here are the six mistakes that cost the most, and what to do instead.

The Short Answer

The title is blunt on purpose. Your IIM call does not depend on exam day alone, but exam day is where most of it is set. Your CAT percentile is usually the largest single part of an IIM's shortlisting score, and it is shaped by habits you follow in the next six weeks. After the exam, your profile and your WAT-PI preparation decide whether a good percentile becomes a call and then a conversion.

So there are two jobs: protect your percentile now, and do not wait for the result to prepare for everything that follows.

Key Dates to Keep in Mind

These dates come from coaching-institute coverage of the official notification. Confirm everything on the official CAT website before you plan around it.

Mistake 1: Taking Mocks Without Analysing Them

This is the most common mistake, and the most expensive. A mock you do not analyse is a few hours spent measuring yourself, not improving.

Coaching institutes suggest 15 to 20 full-length mocks in the last two months, though that varies with your preparation. The number matters less than what you do after each one. For every mock, note:

• which questions you got wrong and why (concept gap, silly mistake, or time pressure)
• which questions you skipped, and whether skipping was the right call
• which questions took too long
• which answers were guesses, and what the guess was based on

One mock analysed properly is worth more than three attempted back to back.

Mistake 2: Watching Only the Total Score

A good overall score can hide a weak section. This matters because the exam has three sections of 40 minutes each, and most IIMs look at sectional performance as well as the overall score when shortlisting. Check each IIM's own criteria for the exact cutoffs.

What to do instead: after every mock, look at VARC, DILR and QA separately. If one section keeps dragging you down, give it a fixed share of your time every week, and use sectional tests for it. Strengthening your weakest section is usually easier than pushing your strongest one higher.

Mistake 3: Changing Your Strategy Every Week

A bad mock in the last month feels like an emergency. Aspirants respond by changing their attempt strategy, switching the order of sections, or dropping topics they had planned to revise. Changing strategy often, without a reason, is one of the common mistakes coaches warn about.

What to do instead: decide your approach to the paper, such as the order of sections and how you pick questions, and stick to it for at least three mocks before changing anything. Treat a bad score as feedback, not as a verdict on your ability. Your sleep, your routine and your stress levels affect your score more than most last-minute topic changes.

Mistake 4: Practising Without Exam Conditions

Relaxed mocks, with breaks, a phone nearby and no strict timing, do not prepare you for the real thing. The real exam has strict section timing, a fixed window, and the pressure of a computer-based test centre.

What to do instead:

• Take full-length mocks in one sitting, in a quiet place, and keep to the 40-minute section limits.
• Take some mocks at the time of day your CAT slot is likely to run. Slot details come with your admit card.
• Practise the small things: a short routine for the first two minutes of each section, and what you will do if you blank on a question.

Mistake 5: Treating CAT Percentile as the Whole Story

A high percentile is necessary at the top IIMs, but it is not the only input. Most IIMs build a composite score that adds your academic record, work experience and diversity factors to your CAT score, and the weights differ from one IIM to another. Because the weights change every cycle, do not rely on a table from a blog, including ours. Read each IIM's official criteria once they are published.

What to do instead, starting now:

• Gather your marks, certificates and work-experience documents in one place, so you are not searching for them later.
• Write down your profile honestly: academics, work experience, achievements and projects. Know where it is strong and where it is weak.
• Read the most recent criteria for the IIMs you are targeting. Our post on IIM Calcutta's MBA selection criteria for 2027 is a good example of what to look for, and our comparison of the top six IIMs helps you decide where your profile fits.

Mistake 6: Waiting for the Result to Start WAT-PI Preparation

If you wait for the result, you start WAT-PI preparation with very little time. IIM calls follow the result, and the interview stage is where many strong percentiles are lost.

What to do instead, in the weeks after the exam and even before it:

• Prepare two or three real stories from your work, studies or projects, each with the problem, what you did and what changed.
• Practise writing short, structured answers on current topics, so the written ability test feels familiar.
• Prepare an honest, specific answer to "why an MBA, and why now?".
• Keep a backup plan. Other entrance exams and B-schools have their own timelines, so check the dates on the official sites. Our posts on SNAP vs NMAT, the MDI Gurgaon application form and FMS vs MDI vs SPJIMR can help.

A Simple Six-Week Plan

This is our suggestion, not an official schedule. Adjust it to your own strengths.

What We Do Not Know Yet

• CAT dates and the result date are based on coverage of the official notification, and we could not confirm the exact result date.
• IIM selection criteria for 2027 are still being published or updated, and the weights change from year to year, so we have not quoted specific numbers.
• The mock numbers in this post are a coaching institute's suggestion. They are a guide, and the right number depends on your level.
• Nobody can tell you the safe percentile for a given IIM in advance, because it depends on the year's cutoffs and your profile.

Frequently Asked Questions

How many mocks should I take in the last six weeks? Coaching institutes suggest 15 to 20 full-length mocks over the last two months. Quality of analysis matters more than the count, so take fewer mocks if you cannot analyse each one.

Should I change my strategy if my mock scores are low? Not after a single bad mock. Keep your approach for at least three mocks, then change one thing at a time if the pattern is clear.

Is a high CAT percentile enough for an IIM call? It is usually the largest part of the score, but most IIMs also use academics, work experience and diversity factors, with different weights. Check each IIM's official criteria.

When should I start preparing for WAT and PI? Before the result. The gap between the exam and the calls is short, so preparing your stories, documents and answers early gives you time to practise.

Do I need to prepare for other exams as a backup? Many aspirants apply to several exams and B-schools. Check each one's official dates and requirements, and decide early so you are not rushing in December.

What if my mock scores are not improving? Look at the analysis, not just the score. If the same kinds of mistakes repeat, fix those topics before taking more mocks.

Final Word

CAT is not decided on the last day alone, but the last six weeks shape most of it. Analyse your mocks, balance your three sections, stay calm with your strategy, practise under real conditions, understand your profile and start your WAT-PI preparation early. Dates, criteria and cutoffs change every year, so check the official CAT website and each IIM's admission page before you decide.
