Colleges in West Bengal

NSHM, Kolkata and Bharathi Vidyapeeth are equally good institutes. Some of the important points while selecting an institute - Accreditation of the institute, institute's infrastructure, teaching faculty, specialization offered, past placements records., tuition fees, city preference and industry interface. As both, the institutes are having the campus in different cities Kolkata and Delhi. Industry exposure is good for students in either of the college. If possible a visit to college is better option to get a reality check. Also, get in touch with college alumni's through the social network to get information about the latest changes if any.
