bms will be the best option

sir according to my view if you are interested in job then start preparing for bank coaching it will help you to crack exam at the earliest. and one thing don't go for correspondence study it only increase your knowledge that's also little bit, it never help you to get job.not even a single good company prefer correspondence study, you should go for professional courses like CFA, CPA cs CA icwai these course help you more settle in life at the earliest. best of luck

You can go with pgdm, as it is very practical course vry helpful in ur carrer also.All d best !!!!

You can join advanced excel to increase your chances at job
You can even try out internships in vacation time
After bcom you can go for CFP or other certification course
CFP right now costs 35000 rs but do it only after a good job in finance sector so CFP can help you

Go for B.com and then pursue your masters in entrepreneurship from NMIMS or IIMs. B.Com will help you in understanding the laws, policies, organisation structure, taxes etc to make you prepare for own business.

B.com hons will be better if you wish to pursue finance later as the course structure is more relavant.
