B.Com

Yes you can, however, the mapping of syllabus will be required.

Hi,
B.Com is a commerce and finance related study, so you can further study M.Com, MBA finance, CA, CS, etc.
BBA is a business administration study - generic as well as with specialisation.

Hi,
The BBA might be a better starting point, as its hooked more towards MBA. Most of the subjects which you will get engaged while doing an MBA, would not be new to you if you go for the BBA course. So, basically MBA is the umbrella course and BBA is the part of it. The B. Com is also a decent course which many students pursue throughout the country. After completing B.com, students go for MBA. But BBA is a specialized course, and there are placements even after completing it. On the other hand, B.Com is bent towards being a generalized course with more focus on commerce subjects.

Since you have completed your class 12th with 86% marks, so getting SRCC is not possible, but you can definitely apply in DU for UG course. There, all you need is to fill up an admissions form, then you will be shortlisted according to the college cut off list.

B.Com is graduation for commerce stream students, you will study accounts, costing, financial management, statistics etc. After this, you can apply for further for post-graduation or any competitive exams like banking, SSC etc.
