Hello Karan

According to your percentile score your expected JEE Main rank would be around 108,118 - 128,118. 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.

It would be difficult to tell you about the  qualifying cutoff for JEE Advanced as JEE main exam is being conductd twice for the first time so nothing can be said clearly before the results of JEE Main April exam.

Good Luck!
