Hi Aspirant

There are several colleges in India which are best for BSc.

Banaras Hindu University

The oxford College of Science(Bangalore University)

Jaipur National University

Aligarh Muslim University

Delhi University

It very much depends on you ,how seriously take the course.Sometimes even if you are in good college you won't be very successful and the reason is lack of hard work.So work hard wherever you are.

All the best.
