B.Com Scope

Dear Anjali,
For your reference, here are the courses:
CA
Chartered Accountancy is related to commerce field. Though you can become a CA right after completing class 12th, this course deserves a mention here.
CS
CS stands for Company Secretary. Like CA you may pursue this course right after class 12th. Still, I think this programme deserves a mention in this article.
CMA
CMA stands for Certified Management Accountant. It is an ideal certification for commerce graduates. The certification will help one find jobs in sectors such as banking, insurance, etc.
Actuarial Science
If you want to become an actuary, this training programme will be of help to you. Commerce graduates may undergo actuarial science programmes. This certification will help them obtain jobs in sectors such as banking, insurance, etc.
Certificate in bank management:
The main aim of this certification programme is to churn our skilled bank managers. A bank manager should have knowledge about banking, finance, economics, accounting, etc.

MCA after B.Com is a good option if one satisfies the following conditions. MCA being a Master's degree (post graduation degree) for computer applications and B.Com being a pure commerce degree.
Nature of job and future:
For students opting for MCA after B.Com to know what kind of work you will be involved in, is important, as you are completely taking a different career path. In general, you would be inducted as a programmer in a company, working on software, systems, network, internet, etc., and gradually with your skills and experience, you will rise in status within the field. Hence, it is important to check out all these factors:
Make sure you are confident of your aptitude/skills matching the requirement of this field MCA before you take the decision to pursue it. You may check the subjects in MCA and get an idea beforehand on what you would be studying
You may also talk with students doing MCA the teachers or any of your friend who is doing this course.
