Hey poulami

As the rank will be announced after combining January and April results.

And it will depend upon the total number of students and percentile .so it is not possible to find rank just now, you have to wait till April.

But for reference and for the preparation of April exam you can predict your rough rank

By:

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

And it is approximately more than 1.6 lakhs in your case ( may vary).

So taking this as reference you can prepare yourself for April exam and you need  a lots of improvement because it is not enough to get admission in NIT OR IIIT with good branches .

Good luck
