As both are the undergraduate programs as B.Com allows students to study subjects like Accountancy, Business Administration, Finance, Economics and Industrial Policies. Also, after B.Com the students can opt for post graduate courses like MBA, LAW, International studies, M. Com, Finance, Economics and so forth whereas BBA is considered to be a professional degree program in which students study all about business administration but this course is of limited availability, as compared to B.Com of which just a modest bunch of universities/ foundations offer quality course. Also, BBA course guarantee's that you graduate with an industry-important degree and once you are done with your BBA then the you can opt MBA as this would be the best combo. Lastly, both the courses are good and have their own benefits so it is advisable to choose the one in which you have maximum interest and in which you can give your best. So decide wisely.

Good Luck!!!
