Hey.

The three courses that you have mentioned are 5 year integrated course of law that combine Law with an undergraduate degree like- BA,  Bcom, Bsc etc. In BA LLB you get an undergraduate degree of BA. In Bcom LLB the undergraduate degree is of Bcom and it's of Bsc in Bsc LLB.

So the subjects that you study along with Law will depend on the undergraduate degree that you choose. It will differ in these 3 courses accordingly. This is the only difference between the three course.

Best of luck
