Hello aakarsh

DU is not a collage. It’s a university/governing body(for UG) that provides guidelines and degree to the students studying in the colleges affililated through DU. There are more than 50 colleges under DU which ranges from one of the best in country to worse also. So, depend on your 12th marks you can get a college that actually belongs to DU. If you want to do B.Sc ., try for the admission in DU only beacause I don’t think there is any other good collage that doesn’t belong to DU.
