Which course should I pursue, B.Com or BBA?

B.Com is much better than BBA because after B.Com you can opt different lines like banking preparation, insurance accountant, etc. But, after BBA only one thing is left and that's MBA. By the way, you can do MBA after B.Com also.

If your long term educational goal is MBA then BBA is better option over B.Com. BBA program usually includes general business courses and advanced courses for specific functional areas such as Finance, HR, IT, Marketing etc. B.Com is a good option if you target career is only in accounting & Finance
