Hello jaya 

I see that you are going through quite a dillemma ,on which subject you should choose. CSE and ECE , both are really good subject , so it totally comes down to what your interest is, what will be suitable for you. 

Coming to college many would think that nit will be good just because it is nit. somewhat it would be true, I also prefer it. But sastra is none less than some nit's , it is also a good college. So both are good

But it's you who have to decide .

All the best.

Thank you.
