It would be difficult to provide you the qualifying cutoff 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 306,541 - 346,541 and your probable category rank range will be 20784 - 22384. With this rank you may be eligible for JEE Advance but chances are less 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!
