It is difficult to predict the actual rank or JEE Advance qualifying marks as first time JEE is being conducted twice and rank will be based on NTA percentile score but you may calculate  your expected rank by given below Formula.

874469 are the number of candidates appeared for the January exam. So rank formula is (100- your total score) * 874469 / 100.

If the number of candidates for April exam increased to 1400000 then your final rank shall be (100- your total score) * 1400000/100.

Good Luck!

Hello Gpa Prithvi

Congrats For Your 76.2553619 percentile in JEE mains.

If we Consider total no of students to be 10 lakh

and apply the formula

Rank =( total no of students -( percentile*0.01*total no of students))

so the expected rank would be Rank = 237446

i hope you get my point

Thank you and GOOD LUCK!!!
