Hii

As of now the final results are not declared. It will be declared after the april session after compiling results of both the sessions. So predicting your exact rank is not possible but yes we can calculate the expected approx rank with a formula given below.
100- your score * 874469 /100
so you use this to check your rank. But remember the rank will change once final result is declared because best of the two scores will be used and also the number of students can increase in the second session.
You can also use the following link to check your rank-
