Only percentile score is declared by NTA which tell about remarela performance of candidate in session.You can get rough idea about your rank in genral category::Probable Rank= (100- NTA percentile score) X 874469 /100.This will gives you Probable rank in general category.May be you can qualify with this percentile in OBC category.But for assurance wait.

Wait till NTA declares raw score and cuttoff marks for each category.NTA will decalres rank and raw score after 2nd phase of exam.

You still have a attempt for jee mains.

GOOD LUCK!

The cutoff percentile for JEE Mains Entrance Examination is not yet announced by National Testing Agency (NTA). Also this year JEE Mains examination is happening twice in various shifts on various days so the exact cutoff percentile cannot be estimated.

I suggest you to wait for the officials to announce the precise percentile. 

If you have any other query do mention it down in the comment section.
