Hello

It is difficult to predict the actual rank or JEE Advanced qualifying marks as for the first time JEE Main is being conducted twice and rank will be based on NTA percentile score.
You may calculate the expected rank by this 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

According to the above formula, your expected rank will be around 174893.

Nothing can be exactly said about the qualifying percentile till the April exam.

Good Luck!
