Hello Aspirant,
JEE Main 2019 is being counducted twice by NTA for the first time so It would be difficult to provide you the qualifying score or admission cutoff. Based on this score the chance seems less to get a seat in NITs. You Can also use JEE Main College Predictor tool to know your admission possibilities.
