As an OBC category student to get calls from top IIMs like IIM A, B and C you need to have above 98+ percentile. For other old IIMs like IIM K, L and I you need to have above 95+ percentile and 97+ to increase the probability of your conversion. To get a call from all new IIMs and ultra new IIMs you need to have 92+ percentile.

There is again no surety of selection or getting a call from these colleges because CAT marks are not the only parameter involved in the selection procedure. After CAT exam every college in which you have applied prepares a merit list to call students for next round of interview based on your aggregate score which comprises of many parameters such as CAT marks, 10th, 12th and graduation percentage, work experience, engineer or non-engineer whose weightage varies for all different colleges.

And after your second round of interview again a new merit list is made which also includes marks of your interview, GD and WSAT which along with CAT marks generally have the highest weightage.

So along with a high percentile, you need to have an overall excellent profile. All the best!!

Hello,

The cut off for CAT to get admission in any IIM's for OBC-NC is 80-90 percentile.

For IIM A the cut off is 75+ percentile, for IIM B the cut off is 80+ percentile, for IIM C the cut off is around 85 percentile. 

For IIM Indore, IIM Visakhapatnam, IIM Kozhikode the cut off is around 80 percentile. 

To increase the possibility of getting a call for the top IIM's of India, you need to score 90+ percentile. If you score 90+ percentile you will get call from IIM thats for sure. For admission in IIM's, CAT percentile is not the only criteria which matters, you need to have a good academic background and work expericence which will increase your chances of getting selected. You know the final merit list is bvased upon your aggregate score which includes your CAT percentile, Academic performance in 10th & 12th, your graduation and your work experience. 

Always set your goals high so that even if you under perform you are on the safer side. Score atleast 90+ percentile to get into better college. 

All the Best !!
