It would be difficult to provide you the exact information about the admission possibilities as per the score as JEE Main 2019 is being conducted twice by NTA for the first time and rank will be based on the NTA percentile which will be decleared in the month of April.

Based on this percentile the chances seems less to get a seat in NITs, I would suggest you to appear for JEE Main April Session again.

If you want to know about JEE Main Paper II then let me know.

Good Luck!
