Hello Nikhil,

It would be difficult to tell you the exact about the qualify marks as JEE Main is being conducted twice by NTA for the first time and NTA Scores for both of the attempts will be taken into consideration and the best of the two attempts will be considered for ranking purposes.

Based on your score your probable rank will be 468,873 - 533,873 and your probable category rank range will be 37000 - 41000. 

NOTE: The Overall Rank Predicted is on the basis of the expected total number of students i.e. 1152650 appearing in the JEE Mains 2019.

Good Luck!
