Hello,
As per last years cutoff, there are no chances of getting a seat in top NITs. https://engineering.careers360.com/articles/jee-main-cutoff-for-top-nits
I will suggest you to go for state counseling like M.P, Haryana, Punjab, etc to get into your desired stream. Also you can use the college predictor tool to know about the colleges you might get based on your JEE rank. https://engineering.careers360.com/jee-main-college-predictor?icn=QnA&ici=qna_answer
