For XLRI, you have to appear for XAT.You need to score 96 percentile and above to get a call for BM and 94 percentile and above for HRM. Besides you also need to clear sectional cut-offs.

IIMs take admission through CAT. I am assuming you are from general category. Based on your overall academic profile, you will need to score atleast 99.4 percentile to get a call for the next round.

All the best!

In order to get the call for further admission process from IIM or IIT, you have to score a very good percentile in CAT entrance i.e. 95 percentile or more. Same is the case with XLRI you have to score very good marks in the entrance.
