Dear Student,

For doing any course and specifically a graduation course you first need to pass out 12th which you haven't. There's no option of course in 12th or after 10th. You'll have a option between Maths, Science and Commerce stream though. But for doing a course which is basically meant for graduation course such as B.com, BBA, B.tech, etc.  You first have to necessarily complete your 12th. Hope this answer might help you.
