As you said you are a MPC student, I would suggest you to go for more better field's rather then bcom BBA. Go for engineering, CA or more better field's you will have more better opportunities in life.
.
Now, inbetween BBA and B.com go for BBA, BBA is particularly focused on business field but b.com is focused on varies subject. BBA students get a better job by holding a graduation certificate but a B.com student need MBA or any higher study certificate for getting a better job. So go for BBA it has wider scope.
