The students efforts will be evaluated on the basis of his/her performance/achievement in different walks of life.
The evaluation will be made by the panel of experts/teachers, preferably interdisciplinary to be appointed by the vice chancellor of the university on recommendation of the dean academic affairs. A faculty counselor will be attached to a group of students which will remain associated with him/her during the entire period of the degree program in the university. Each faculty member will serve as a faculty counselor. They will act like a local guardian for the students associated with him/her and will help them in terms of carrier guidance, personal difficulties.
