Hello,  

You can do MBA in any specialization. The minimum eligibility is an Undergraduate degree with 50% marks from a recognized university and good percentile in the national level entrance test or admission seeking institutes tests like LPUNEST(Lovely Professional University), DSAT (Dayanand Sagar university)and SRMJEEM(SRM University).

Hope this information will help you. Best wishes. 

Good Luck!

Yes, you can go for Financial Management as well. Your graduation degree doesn't affect your MBA streams that you wanna choose. But i will definitely say one thing while being placed a person with the background of accounts would be preferred over you.
So if you are thinking of pursuing MBA keeping placements in view, do rethink on opting for Financial Management.
There are colleges offering PGDM in Hospitality Management, you can consider that as an option if you are not much interested in your core subjects but the overall Hospitality Management overall.

although the graduation stream does not really matter when you are applying for an MBA but anyone from either accounts ,commerce and economics background will be preferred over you in cases of selection to MBA courses especially in the field of financial management.
Since you are  from BDS background I would definitely recommend hospital management as a probable and favourable MBA course for you as compared to financial management where you will will be lacking the basics of those people have invested the years in economics and commerce related studying instead of you has been made to the hospital setup and medical sciences for the same period of time

Dear Jeya, with BDS as your qualification you can pursue MBA in General Management. For pursuing MBA in General Management, you should have completed your Graduation in any discipline with a minimum aggregate of 50%. It is 40% for Reserved Categories. Few Institutions conduct Entrance Examination while few conduct admissions based on merit in your highest qualification.
