Hello Udit

Your percentile suggests that you performed better than 77.4% of people who appeared for the paper that year. As much as good it sounds, it also means you are behind some 2 lakh candidates, and as a result, you most likely wouldn't make it to JEE advance.

You can calculate your score by following this formula:

Rank= (100 - your total score)*(874469/100)

Though you can't expect IIT's, IIIT's or NIT's for engineering, there are also private institutions that consider JEE main ranks for admission along with your 12th board's percentage. Eg: PSG Tech, Sastra University, Amity University

If Engineering is your aim, yes, there's plenty of scopes, even without JEE.

If IIT is your aim, sorry, better you prepare for next mains in April.

Hope it helps.

Hello.

Your percentile score is a bit low and the chances of getting a seat with this score are quite slim. It's best that you reattempt the exam in April and try to improve your performance.

Good luck!
