Hello,

It is true that more than 90+ percentage in academics will get call from IIM if they score 90+ percentile in CAT but Average academic record is not a barrier in getting IIM.your marks is not good but not that poor either try to score more than 99 percentile to get call from top IIMs.if you score 97 percentile you can get call from old IIM'S like IIM lucknow,IIFT,FMS DELHI.

Instead of pondering over which college you get focus more on your studies to score as much as you can to get top b schools.
