Hey.

Yes, your post graduation degree's aggregate can be considered for eligibility of DU LLB. You are required to have atleast 50% marks in your degree which can be graduation degree as well as Post Graduation. So if you do not have 50% marks in UG degree but have more than 50% in PG show, then yes you are eligible.
