Hey Nazrina.

The eligibility criteria for most of the Universities/ Colleges for admission in the 3 year LLb course is that you need to have completed any Undergraduation course from a recognised University, and not LLb degree. As you've not mentioned the college that you're  seeking admission in, I can tell you that you need to have any UG degree like BA, BCOM, BBA, BTECh etc from a recognised University to be eligible.

You might be required to score a minimum aggregate of 45-55% marks in your UG degree to be eligible depending on the college.

Best of luck
