I am assuming you are from general category. Based on your overall academic profile, you will need to score atleast 99.9 percentile to get a call for the next round.

All the best!

To get into IIM A specifically, You need to score 99.6 percentile above as this is the cutoff there and also past academic records are considered which you seem to have average.

be prepared for the entrance and interview rounds. you can expect your admission in IIM's but difficult is IIM A.

Good Luck!
