Hi,

I hope you are doing well.

As a B.COM (//B.COM) graduate or a student with pursuing CA which usually involves fields such as Finance, Accounting,  Banking and Finance.

So, further while you are pursuing you could go ahead with MBA with specialisation in Finance as you have already covered those topics and this area would be strong for you in your graduation.

You could also specialise in Banking and Finance in your MBA.

I hope the above information helps.
All the very best.
