Hi! The difference in the colleges is depending on the various criteria could you please specify me the ways by which you want to sort the college.
Otherwise you can use the college compare tool which is an easiest way to sort the college.

Thank you

 dear student, Government Medical College Suryapet is better than Government Medical College Nizamabad and Mamta Medical College.  It is so because the faculty is lot better in Suryapet Medical College. Even the campus, fest and other facilities like labs are better in this college.
