Hi,

If you have chosen Commerce stream in 11th standard then you will be studying accounts, commerce, economics, business studies, etc as a part of your syllabus. After 10th board, you can choose science or commerce or arts. There is no stream called business studies & in Commerce stream, you need to study business studies as a part of your course. You cannot choose to only study business studies in ISC. So, in this case you don't even get to decide which is better. Business studies is a part of the entire commerce stream like Chemistry is not better than Science. If you study in science stream, you study chemistry as a part of the syllabus.

Hope you got some clarity.
