Hi Sunita,
Congrats on your graduation. If you are looking in for building up your education, then start preparing for MBA as that is a best option with B.Com to face the corporate field easily.

If you are to start up working now then you can start writing the bank exams and preparing for the same as it has lot of opportunities as well as a safe and growing market. That will help you to get settled well in the future. So start preparing to crack up the bank exams and put yourself in a good position in the banks. But you must also do a post graduation as that is more important for your future. Enroll for an MBA in distance education and complete it as you work along.

Thanks
