Class 12-Commerce

You have a decent score. Though getting admission won't be such a big deal for you yet I advice you to apply to multiple colleges to secure your chances better.

It would be better to take BBA because in BBA the depth of the syllabus is less in maths compared to B.Com. You can easily manage the subject by giving little more effort apart from other subjects. Or if you are interested take B.A. Courses especially B.A. Journalism and Mass Communication, it has a very good scope now-a-days.

Hi,
You can do B.Com after class 12th.
