I am appearing for CAT2017 and What should be my percentile and marks in The CAT Exam to get into top IIM's?

You have an excellent profile with excellent academic records which will give you an edge to get calls from any college.

In the OBC category for the top 3 IIMs i.e. IIM A, B and C aim for above 99+ percentile to get a call for interview and WSAT round. Even though after scoring above 99 you will get call from IIM A and C but not sure about IIM B because Bangalore gives a very high weightage to work experience and 3 months work experience does not earn you anything. You wont even get additional marks in your aggregate score due to work experience.

For other old IIMs like IIM L, K and I you need to score above 97+ percentile. With above 93+ percentile you will get calls from all New IIMs. Always aim for a higher percentile, it will also increase your probability of converting your call because the final merit list made by each IIM after interview and WSAT round generally has highest weightage of CAT, interview and WSAT marks.

You have a very good profile it will.help you in long run even during placements after getting selected in any IIM so work hard get a very high percentile and convert your call.

All the best for your preparations and exams!!

You have decent academic scores. So, a percentile above 96+ will get you calls from almost all IIMs considering the OBC certificate. However you might not get a call from B as work ex is given a lot of importance there. But that should not be your aim. You should aim for a 99+ percentile which will in turn also increase your chances of getting into any IIM you want. For a call from A you will require 98+.

Practice as much as you can and give mock tests. It's the best way to increase your speed and let you know where you stand and how much more you need to work upon and where.

All the best!
