Dear Aspirant,

With 99.67 percentile in JEE Mains 2021 CRL Rank would be around: 3376 - 3795

JEE Mains Rank predictor tool:

Now this is a quite good score and rank, considering SC category & according to previous year records of closing ranks there are  chances for CSE Seat in NIT Warangal, NIT Trichy and all other NITs.

If you don't avail SC Category then with this CRL Rank you might get CSE Seat in NIT Trichy if you belong to Home State quota , if not you may get other branches like Electrical  and Electronics(EEE) , Electronics  and Communication Engineering (ECE) in NIT Trichy as well as NIT Warangal.
