Hi,

A General Category candidates need to score a minimum of 95+ percentile score to get NITs. For reserved category candidates, 80+ percentile score is enough to get NITs.

As the cut off percentile for being eligible in JOSSA counselling is 50 percentile for General category you will not be eligible for any NIT or IIT.

You can try to give other engineering exams like WBJEE, VITJEE etc or try for JEE next year.

Hope this helps

Wish you luck
