I am a BBA student and want to study LLB, can you provide some guidance?

If you really want to pursue LLB, then only central universities are good option such as DU, BHU, AU, LU.

Hi, Please confirm the university name in which you want to enroll, because admission process varies for different college. However, to appear for LLB, mostly colleges have their own entrance exams, you can check the same on the respective university website. Regards.
