Tamil Nadu

Manipal seems to have a bad reputation to the outside world somehow but trust me once you come here its nothing like the stories you've heard. It's a lot better than what people think. It is not different than any other college. I suggest Manipal would be a better option and VIT Chennai is a new campus and is small and had limited facilities. Faculty of MIT is well experienced. You wont regret getting admission in this college.
