IIM Ahmedabad - Indian Institute of Management

The 3 key secret to score excellent score in verbal (provided you have your basics right) is: practice, practice and practice. Hence, I would suggest you to first get your basics right by going through the prep materials for verbal and then enroll a test series SIMCAT/AIMCAT and keep practicing the RCs and grammar questions. Try not to commit the same mistake twice while practicing. With time, your verbal scores will improve.

Re-appear would not be a hindrance in your admission provided you cleared it and rest of the exams with a commendable percentage. As IIM A is more biased towards your academics, a good score is a kind of pre-requisite for the same.

You have to clear CAT to secure an admission into IIM A. Kindly find the selection process of IIM A: https://www.iima.ac.in/web/pgp/apply/nri/admission/selection-process

If you want exact numbers then I would suggest that you file an RTI. For a ballpark figure, I would guess it would hover around 85-90 percentile.

Your profile is exceptional for being a prospective IIM-A PGP student. I would suggest that you should study hard and try to score more than 95-97 percentile in CAT to get a call from IIM-A.

Your academics are below average for IIM-A. I would suggest that you try your best for colleges like FMS who do not give any weightage to academics, unlike IIM-A.

Your academic record is tad bit below average even for OBC category. I would suggest that you should give your best and score above 99 percentile or more to expect an admission call from IIM-A, B or C.

To be eligible to be considered in the screening process, your graduation CGPA equivalent should be more than 50%.

Your B.Tech score is below par for your admission into IIM-A. But otherwise, work experience is never mandatory to get admission into any B-Schools in India baring a few.
