No if you belong to general category

well this will get you no college except you are st/sc but you can try a private one

See for general category your JEE main score for getting NIT's is very low. You have rare chances of getting NIT's. You can try in your state NIT where your chances are more. Here I'm talking about core branches, if you looking for other branches then your chances increases. you can get government colleges easily. You can also try in some private colleges and universities like BITS, LPU, VITS, SRM, etc

You can get admission in state government engineering college.

NSIT doesn't have civil engineering and with these scores I don't think you will be able to get computer science.

Maybe it is possible because you are obc.but the frequent chances are no.i think u should better ho for wbjee or other state board colleges
