Hi, last year the highest marks scored in the entrance were 305 which made around 80% in unreserved category. The entrance based merit list is released for every category. So in order get into 1st tier colleges you should score more than 270 marks out of 400

In order to check the merit lists for both entrance based admission and merit based admission, visit the du link: http://www.du.ac.in/pg-admission-lists.html

Good luck
