JEE Main 2019 is being conducted twice by NTA for the first time and the rank will be based on NTA percentile so the exact prediction would be difficult.

Based on this score your probable rank will be 740,854 - 805,854. You may not be eligible for JEE Advance.

Note: Rank Predicted is on the basis of the expected total number of students i.e. 1150000 appearing in the JEE Mains April Session.

Good Luck!
