It would be difficult to provide you the exact information about the cutoff or admission chances as JEE Main is being conducted twice by NTA for the first time.

Based on this score your probable rank will be 278,945 - 308,945,  With this rank the chances are less to get a seat in NIT Trichy, I would suggest you to appear for JEE Main April Session again & try to score well to get a seat in NITs.

NOTE: Rank Predicted is on the basis of the expected total number of students i.e. 1152650 appearing in the JEE Mains April Session.

Good Luck!
