The exact prediction would be difficult about the qualifying marks or rank & admission possibilities as for the first time JEE Main is being conducted twice by NTA in multiple session.

Based on your NTA percentile score your probable rank will be 249,383 - 279,383 and your probable category rank range will be 85743 - 93243, You may be eligible for JEE Advance but chances are less to get a seat in NITs. I would suggest you to appear for JEE Main April session exam again.

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!
