Hello 

As exact rank can not be calculated because it will vary depending upon the total number of students in April exam and how many students score same percentile.So exact rank will be shown after the April results only.

But we can predict a rough idea about the rank by 

Rank= (100 - your percentile) * total number of students /100

And it comes out to be approximately more than 80-90 thousand.And this rank is not enough to get seat in good NIT or IIIT with core branch.

So you should work hard and improve your score in April attempt 

Good luck
