Your academic profile is below average and it could or perhaps would be a hindrance for admission in top IIMs. The only way you can counter the same is by scoring exceptionally well in CAT. For the top 3 IIMs you may need to be a 100 percentiler. 

All the best!

Hii Ravi

Seeing your academic profile, yeah, you can definitely apply for CAT. For getting admission in any IIM, you have a minimum cutoff required.Now you need to really score well if you want to get into one of the top IIMs. 

You need 97+ percentile to get into the old IIMs and for new IIMs, you need a percentile above 90

Goodluck!

Your score must be good in CAT to get into IIM.
