You can go for professional courses like CA, ICWA, CS, CMA. These courses give great careers. But you need to be more hard-working and have lot of patience to study them. They are challenging courses.
Or, do an MBA in a reputed college and get placed. This is also a very good option and most preferred option because you will settle in 2 years.
You can also do M.com or apply and prepare for bank jobs.
Ultimately, what matters is your interest to do a particular course.
All the best.

B.Com has a good scope and you can get a job of an accountant after completing UG. You should pursue CS along with B.Com to get better job prospects.

Basic and fundamental knowledge of required subjects is must to qualify CS (ICSI). Tax is also an important subject of CS (ICSI). By this view, you can prefer to opt B.Com taxation over B.Com Sales management.

The minimum eligibility criterion for admission to B. Ed. is that the student must be a graduate in any discipline. The candidate must either have a Bachelor of Arts (BA) or Bachelor of Science (B. Sc.) or Bachelor in Commerce (B. Com.) from any recognized university with at least 50% marks in aggregate.

You cannot manage articleship and b.com together unless you are doing B.Com from correspondence.
However, you can start your articleship after your graduation completes. It might seem as if there is too much on your plate, but believe me it's doable.
