Ashish, there are 20 IIMs and the old IIMs atleast need 90 percentile for SC Category to be shortlisted. But the new IIMs will need atleast 85-90 percentile. Again these are the minimal percentiles. Though your sectional criteria is really good, your Overall percentile is a tad less. So our suggestion would be is to try for new IIMs. Also try for IIM Kozikhode whose required percentile for SC Category is lesser relatively than the conventional and older IIMs.

With your Academiccs, you might be able to pull it off atleast in the New IIMs and more importantly IIM K. You can even make it to IIM Nagpur to be specific. But again as you know every round is subjective to shortlisting, so Good luck.
