Hi

If you're really willing to study hard then the best choice of colleges has to be any one of the IITs. In India, no college can beat the experience and placements of IITs.

If not IITs then you can try for NITs.

The fees of these colleges is also not very mych.

Other colleges are

Delhi technological University

Netaji Subhas Institute of Technology

Birla Institute of Technology and Science, Pilani

Hope this answer helps!
