subjact changing : maine 12th commerce se ki h or ab main ba krna chahta hu to kya mujhe krni chaiye

Hello

You can pursue B.A after having commerce as subject in 12th standard as there is no set eligibility criteria that restricts you to do so.

Have a look at the colleges available for you offering B.A: https://www.collegedekho.com/arts/ug-arts_specialization-colleges-in-india/

Since you were a commerce student, you probably must've missed out on the basic concepts of the arts subject, so you might have to work a little harder to match the other students. We suggest you to also check out for other options in the commerce field like 

• B.Com 
• B.Sc.
• C.A.
• BAF
• B.B.A.
• B.B.I.
• B. Com + MBA etc.
