NIT

Your son can choose any NIT for B.Tech CSE, but it all depends what your son scored in JEE Mains and what your son's rank is.

NIT would be difficult, but you get a government college.

Congratulations, you have scored quite good marks and you will surely get a seat in one of the NITs. And, NITs have state quota for the students of respective states. So, if you belong to any one of the states, where NITs are situated, then your chances of getting a seat in NIT will be easy.

Hello Prashant,
Sorry to say, but you didn't scored enough to get seat in NIT as the cut offs for NITs for any branch is very high as compared to other colleges If we have a look on previous year cut off in general you need to score below 40k to get into NITs and below 20k to get into top NITs. All the best for future!
Thanks :)

You should at least score 75% or be in the top 20 percentile of your boards to get a seat in the NIT with 240+ marks in your JEE (Paper 2). .
