Hello,

As per last years cutoff, I cannot see chances of getting a seat in top NITs. You can see last years cutoff for reference.

I will suggest you to go for other state counselings, many states like Maharashtra, M.P, Punjab, Haryana, U.P, etc. conduct their state counselings every year and provides admission in many well reputed private as well as government colleges.You can predict your colleges based on your rank using college predictor tool, you will get all possible predictions of the colleges you might get in JoSAA counseling and other state counselings.
