Accounting & Commerce

Yes, you can directly pursue CA-IPCC only if you have completed your graduation and you have secured an aggregate of 55% throughout in your graduation.

You can do MBA in finance and specialise in investment banking risk management portfolio or financial markets. Apart from that, you can pursue certified courses like CFA, CFP, FRM or CMA.

It's up to you, what your area of interest is and your aim, in which field you want to take your career, etc.
You have number of options to choose:
If you got good percentage, somewhere more than 85% then my suggestion is you should go for regular college in DU and after that MBA through CAT/XAT.
Or
You can go for professional courses such as CA/CS/ICWA along with graduation from correspondence.

You need to complete your post-graduation first and then go for B.Ed. degree.
