MBBS to IIM Ahmedabad: Jayesh Bansal's 99.71%ile CAT Story

How Jayesh Bansal Went From MBBS to IIM Ahmedabad With 99.71%ile in CAT

After completing MBBS, how many students jump towards other domains? Most of them either go for MD or settle in their doctor jobs. But Jayesh Bansal took a turn and achieved 99.71%ile in CAT 2025 and covered IIM Ahmedabad. What might be his motivation?

After spending years away from mathematics, he returned to the subject for CAT preparation with plenty of uncertainty. His journey was not built around an engineering background or years of mathematical practice. Instead, it involved courage, curiosity, consistent effort, and a clear reason for pursuing an MBA.

Why Did a Doctor Leave Medicine and Choose an MBA From IIM Ahmedabad?

For Jayesh, the decision to pursue an MBA did not emerge from a conventional career roadmap. Medicine usually follows a familiar path: MBBS, postgraduate studies, and possibly super-specialisation.

Stepping away from that route therefore required a different mindset. Jayesh described his MBA instinct as something natural and intrinsic, rather than something influenced by a specific precedent.

He had seen doctors pursue management before, although the path remained relatively uncommon compared with engineering backgrounds.

Jayesh explained that moving deeper into medicine could mean narrowing his perspective further.

“I want to go into the business line of things and have my own venture.”

For him, management offered exposure to business, strategy, people, and opportunities beyond medicine.

Maruti Sir also highlighted an important point about medical diversity at IIMs. Doctors remain less common than engineers, but they are not unheard of across IIM batches.

That difference can become an advantage when you build a strong profile and communicate your story convincingly.

CAT Preparation After 9 Years Without Mathematics: How Jayesh Overcame the Challenge

Returning to mathematics after nine years was one of Jayesh’s biggest concerns before CAT 2025 preparation.

His concern was straightforward: Could someone from medicine really cope with the CAT syllabus after such a long gap? However, the answer came through his CAT 2025 result.

Jayesh eventually scored 99.78 percentile in both DILR and QA, proving that a medical background does not automatically create a barrier.

Jayesh’s experience also highlights an important CAT preparation principle: familiarity matters before speed.

If a concept feels completely alien, solving questions quickly becomes difficult. However, once fundamental ideas become familiar, practice becomes far more productive.

This is where a structured CAT preparation strategy can help. Start with the CAT syllabus, understand the major topics, and gradually move towards CAT PYQs. You should not measure progress by comparing your first mock with an engineer’s tenth mock.

Instead, use CAT mock tests to identify gaps, while using CAT PYQs to understand the actual question patterns. The goal is not instant mathematical mastery. The goal is to make unfamiliar concepts familiar enough to solve under pressure.

How Jayesh Scored 99.71%ile in CAT Despite Coming From a Medical Background

Jayesh’s VARC percentile stood at 92.59, while DILR reached 99.46 and QA reached an exceptional 99.87 percentile. That combination resulted in an impressive 99.71 overall percentile.

You need to build enough strength across sections to protect your overall percentile and meet sectional requirements.

For a doctor returning to mathematics after years, scoring nearly 99.8 percentile in QA is especially significant. It shows why you should not label yourself according to your academic background before attempting the exam.

What CAT Aspirants Can Learn From Jayesh

• Do not fear the CAT syllabus because your academic background looks different.
• Start with fundamentals instead of jumping straight into difficult questions.
• Use CAT PYQs to understand how concepts are tested.
• Use CAT mock tests to improve speed, accuracy, and decision-making.
• Track your weaker section instead of ignoring it completely.
• Build confidence through measurable improvement rather than assumptions.
• Treat unfamiliar topics as gaps to fix, rather than permanent weaknesses.

For doctors specifically, the transition may initially feel like walking onto unfamiliar ground. However, medicine itself teaches you to absorb large volumes of information systematically.

That ability to learn, revise, connect concepts, and work under pressure can become valuable during CAT preparation.

Jayesh’s CAT Interview Experience: What Helped Him Convert IIM Ahmedabad?

Jayesh’s IIM Ahmedabad interview lasted approximately 20–22 minutes. Interestingly, the panel did not spend excessive time discussing his decision to pursue an MBA after MBBS. The conversation moved quickly towards current affairs and mathematics.

The interview experience demonstrates that IIM interviews are not simply question-answer examinations.

Your response to an unfamiliar question can reveal confidence, honesty, composure, and willingness to learn.

The Biggest CAT Interview Lesson: Why Confidence Matters More Than Perfect Answers

Maruti Sir shared a particularly useful observation about IIM interviews.

“It’s not about the questions or the answers they ask.”

The panel is also observing how you behave throughout the interaction. They notice whether you become nervous after a difficult question. They observe whether your explanation sounds genuine and whether your confidence remains stable.

Jayesh experienced this directly when he faced an uncomfortable mathematics question. Instead of inventing an answer, he admitted that logarithms were not an area he was comfortable with.

That honesty did not mean giving up. He also communicated that he was genuinely interested in learning mathematics. That balance matters.

You do not need to pretend that you know everything. You need to demonstrate that you can handle not knowing something. If an interviewer catches an exaggerated claim, one weak answer can become a much larger problem.

How Jayesh Handled Tough Maths Questions in the IIM Ahmedabad Interview

Jayesh was asked about the graph of y = log x / x, despite his medical background. Rather than bluffing, he clearly told the interviewers that he was uncomfortable with the question.

This approach is especially useful for doctors appearing for IIM interviews.

You may encounter finance, economics, mathematics, or business questions that feel distant from your academic training.

Your job is not to manufacture expertise. Your job is to think clearly, communicate honestly, and remain composed.

Why Non-Verbal Communication Can Make or Break Your IIM Interview

While discussing with Jayesh, Maruti Sir placed strong emphasis on non-verbal communication during interviews.

According to his experience, body language can communicate confidence even before your words are fully processed. Interviewers can observe your posture, expressions, eye contact, hesitation, confidence, and manner of answering.

“Most of it is communicated through non-verbal communication.”

This does not mean you should rehearse artificial gestures before your interview. Instead, focus on being comfortable with your own story.

If you genuinely understand why you want an MBA, your answers become easier to communicate. If you are merely memorising responses, pressure can expose the gaps quickly.

Three Things to Practice Before Your IIM Interview

Jayesh’s interview also reinforces another point: your interview is an interaction, not a courtroom examination. Treat it as a conversation where you demonstrate how you think.

What Should Doctors and Non-Engineers Know Before Preparing for CAT?

A medical background does not automatically limit your opportunities after an MBA. However, your profile can influence which roles shortlist you during summer placements.

• Decode the CAT syllabus: Start by checking the complete QA, DILR, and VARC syllabus. Mark familiar topics and identify areas requiring additional revision.
• Rebuild your basics: Revise fundamental mathematical concepts before attempting advanced questions. Strong basics make difficult topics easier to understand and apply.
• Use CAT PYQs: Solve CAT previous year questions topic-wise after completing each concept. This helps you understand the difficulty level and recurring question patterns.
• Take CAT mock tests: Once your basic preparation is complete, include CAT mock tests regularly. Use your scores to check accuracy, speed, and question selection.
• Maintain an error log: Record every incorrect or skipped question along with its reason. Revisiting these mistakes can prevent the same errors from appearing repeatedly. Use Cracku’s error log tool to identify weak topics and reattempt those questions.
• Improve question selection: CAT rewards smart decision-making, not just calculation speed. Learn to identify questions that offer a realistic chance of solving within a limited time.
• Strengthen weaker sections: Do not completely ignore a weaker section because another area feels comfortable. Give targeted practice to improve accuracy and maintain sectional balance.
• Increase difficulty gradually: Move from basic questions to CAT-level problems instead of starting with the toughest questions immediately.
• Focus on consistency: A regular preparation routine can gradually rebuild confidence, especially if you have been away from mathematics for years.

Jayesh’s Advice for Students Joining IIM Ahmedabad: What to Do Before Day 1

Jayesh admitted that he was unfamiliar with the MBA curriculum and wondered whether he could cope.

Maruti Sir responded with practical advice instead of suggesting months of intense pre-MBA study.

The first recommendation was simple: understand what you are about to study.

Pre-IIM Preparation Checklist

Understand the Curriculum

Maruti Sir recommended downloading the first-year curriculum before joining. You should know the subjects taught across the terms and understand their broad purpose.

You do not need textbook-level mastery before Day 1. You simply need enough Awareness to avoid feeling completely lost during your first classes.

Give Accounts Extra Attention

For a non-commerce background, accounting deserves additional attention. The objective is not to master every accounting concept before IIM.

Instead, learn the fundamentals so that classroom teaching does not begin from zero. He compared this preparation with mathematics: understanding factorials makes permutations easier to learn later. The same principle applies to accounting.

Become Comfortable With Excel

Excel is another practical skill worth developing before joining. It is relatively easy to learn and can become highly useful during an MBA.

Maruti Sir explained that strong Excel skills can save valuable hours during an already hectic academic schedule. That time can then be redirected towards academics, clubs, competitions, internships, or simply getting enough rest.

Build Your Master Resume

The placement committee may ask you to prepare a master resume soon after joining. This document should contain everything meaningful you have accomplished.

Do this before joining if possible. Once the academic rush begins, searching for old certificates and achievement details can become surprisingly painful.

Connect With Seniors

Speak with seniors before joining. Ask them about courses, expectations, workload, and useful resources. You do not need to study for several hours every day before IIM.

Even one focused hour of preparation can create familiarity before classes begin. You should not enter IIM with the sole objective of collecting contacts.

Relationships naturally develop through classes, hostels, clubs, competitions, common friends, and campus activities.

Over two years, you may learn about your batchmates' backgrounds, internships, work experience, interests, and career paths without deliberately forcing conversations.

That network can become valuable years later. Suppose you want to move into a large company after graduation. You may not know the hiring manager directly, but an alum could know someone from your batch.

MBBS to IIM Ahmedabad Jayesh Bansal's CAT Story: Conclusion

Jayesh Bansal's MBBS to IIM Ahmedabad journey demonstrates how an unconventional academic background can be approached strategically during CAT preparation. Despite returning to mathematics after around nine years, he scored 99.71 percentile in CAT 2025 and eventually converted IIM Ahmedabad. His experience highlights the importance of rebuilding fundamentals, practising consistently and refusing to treat an academic gap as a permanent limitation.

His journey also extends beyond the CAT score. From remaining honest during difficult IIM Ahmedabad interview questions to preparing for the transition into management education, Jayesh's experience offers useful lessons for doctors and other non-engineers considering an MBA. The strongest takeaway is simple: your previous academic background shapes your starting point, but your preparation determines how far you can go.
