Hey.

If you are interested in pursuing law after completing School, then you should opt for Arts stream if you want to pursue BA LLB course. The subjects you will study in Arts stream will be helpful while you pursue the BA LLb course.

If you are more interested in Commerce subjects then you can pursue BCom LLb, BBA LLb too later on and choose commerce stream in class 12th.

The science stream in 12th is less recommended as compared to other streams.

Best of luck!
