Business Management after Science?
Yes, you can go for business management.
Depends upon whether you want you can do courses related to business management directly after 12th or do it after graduation.
You can do BBA or BMS, if you wish to pursue management after 12th.
Alternatively, you can do graduation, in say, Science (B.Sc) or Engineering etc., and then do an MBA.
You need to remember that if you get in to business management after 12th, you need to be very focussed and determined to do your MBA later.
Otherwise, taking up BBA or BMS would not make much sense.
However, if you are unsure and want have more options, then taking up Graduation could be better.
