Hey there

You have a decent score in your academics but iimk has very high Cutoff and thus you'll have to aim for more than 99 percentile. But that too will not guarantee your selection for the college. It is possible that candidate who gets call from iimk may be rejected there. For any IIM atleast more than 98 percentile is required as different IIMs have different criteria for call.

Check iimk cuttoffs
