Both BBA (Bachelor of Business Administration) and B.Com (Bachelor of Commerce) can be considered excellent undergraduate courses for a Master of Business Administration, though BBA is preferable to the student who intends to study business management as the first course. BBA gives a more specialised curriculum of studies related to business administration, leadership, and management, which is directly more related to MBA topics. On the other side, B.Com has an outlook of commerce, accounting and economics that can benefit greatly for an MBA student mainly if you are into the finance or accounting areas of interest. It really, therefore, depends on you and your interests in advancing your career.
