Hello. Th ough it is difficult to predict the cutoff or your rank now but any rank below 2,00,000 might get you qualified for JEE Advanced.

You can check your rank from the below link.

Rank- (100-your percentile score)*(874469/100)

According to this your approx rank is 279830.

But remember that this is not the final rank. Your rank depends on your percentile which ultimately depends on the no. of students appearing in April exam. So if the no. of students increases in April attempt (which oviously it will) your rank and percentile will change.

I would recommend you to prepare well for the April exam and try to score 70+ to qualify.

Hope this helps. You can check the below link for more details.
