It would be tough to provide you teh exact information about the admission cutoff as JEE MAin is being conducted twice by NTA for teh first time.

Based on this score the chances are less to get a seat in NITs. I would suggest you to appear again for JEE Main April session.

The above given information is for JEE Main Paper I, If you have the query regarding JEE Main Paper II then let me know.

Good Luck!
