I hope this information helps you.

Good Luck!!

If you score 81.12 percentile in JEE Mains, then your category rank would be around 20,00 in the SC category. It's too tough to get into NIT Silchar with this rank. Therefore, I recommend not solely depending on JOSAA counseling with this rank. You also need to participate in CSAB rounds, which will increase your chances of getting into any NITs or other good government engineering colleges with this rank.
