Hello Karthi,

It is difficult to predict your exact qualifying marks or JEE Advance Eligibility as the exam is being conducted twice in multiple session. The final NTA scores will be used to rank the candidates. But a score of more than 85 percentile should be a good score to qualify JEE Advance.

You can use this formula to calculate your expected rank-

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.
