Hello Chirag

Calculating the marks scored by the candidate in the JEE Main exam from the percentile score would be difficult as the JEE Main exam was conducted in multiple shifts, the raw marks have been converted into percentile scores using the normalization process released by NTA.

According to your percentile score, your expected rank would be around  174,758 - 194,758. The Overall Rank Predicted is on the basis of the expected total number of students i.e. 1150000 appearing in the JEE Mains April Session.

With this percentile score, chances would be less to get admission in NITs.

Good Luck!
