See both the colleges are affiliated by the same university i.e., Jawaharlal Nehru Technological University, Hyderabad . So the curriculum followed by both the college is the same. Now apart from this if you see the placements then MGIT have better placement ration compared to KMIT. Also MGIT have more specialized faculties in the field. So if you choose any one between this two, then as per my opinion MGIT will be better than that of KMIT.
