You dont need any particular subject . All that is needed is a minimum of 50% in your 12th boards.

Hello Aspirant

You want to study business management courses . It is very good platform to be a successful person . There are lots of job opportunity in business management . Now you are in class 11th . My suggestion is now you should take the Science or commerce steam in 11th . You choose subject as per your interest . Then after 12 th you can proceed for BBA for better knowledge of business .

Thanks
