With 90.2 percentile in JEE MAINS it's quite difficult to get into any NITS. You can try in NIT AGARTALA and eastern NITS in some lower branches like biotechnology, industrial, etc. So you need to try in some private universities of the state which have 15% reserved for jee mains -

1. Amrita University
2. Srm university
3. BIT Sindri
4. Lmnit Jaipur
5. Jaypee Noida
6. THAPAR University

Best wishes. Thank you.
