Hi

hope you are doing well

It might be challenging with a  JEE Main rank of 259,793 and an OBC-NCL rank of 90,405, securing CSE at NSUT East Campus (Netaji Subhas University of Technology)

While it is unlikely you'll get CSE at NSUT East Campus with your current rank, you could consider applying for other branches or colleges where the cutoff is more favorable.

You can try in UPCET counselling there you can get many more better colleges

you can refer to this link for better analysis:
