Hey aspirant!

Since the NTA hasn't released the All India Rank and won't do so until the April session results are declared you can only predict your expected rank for January session.

It’s difficult to predict actual rank or JEE advanced qualifing marks. However, you may still calculate your expected rank by this formula:-

100 - your total percentile score is the percentage  of people ahead of you. 869010 are the number of candidates appeared for Jan exam. So rank formula is (100 - your total score) X 869010 /100. If the number of candidates for April exam increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100.

In your case, the expected rank will be around 146436. Now, this is a prediction based on students appeared for January session and is calculated for Jan session only and final rank will be based on your best of 2 scores in 2 JEE Mains sessions.
