Hey Deepa.

Allocation of the choice of course between BA LLb and BBA LLb in colleges in IP University is done based on every candidate's rank and his choice of preference. So normally if you've taken admission in VIPS for BBA LLb, you can't change it to BA LLB as per your own wishes. But in case of any subsequent round of counselling you can get it upgraded or change the stream.  Other than that after the counselling process is over, and there are any vacant seats then the stream can be changed based on vacancies and all those who apply for it. But that also can't be said for sure in advance how many vacancies will occur. But these are the only ways for a change in stream after admission has been done. Other than that, there is not much difference in scope in the two streams. Only the subjects that you study will be different. It won't affect your career choices as much.

Best of luck
