It would be difficult to provide you the qualify score or rank & admission possibilities as JEE Main is being conducted twice by NTA for the first time and rank will be based on NTA percentile score.

Based on this score your probable rank will be 270,427 - 300,427 and your probable category rank range will be 16740 - 18340. With this rank the chances are less to get a seat in NSIT & DTU.

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!
