Hello. You have a good percentile. It means that 6% of tot students appeared in the exam are ahead of you. (Approx Tot. Students appeared- 874469).

Though it is difficult to predict the cutoff for any particular college 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 rank is 52468.

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.

To know cutoff for nits you need to wait till April after NTA declares the overall merit list on 30th April.

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