Hello Priya,
Bachelor of Commerce (B.Com) is a 3-year long undergraduate course that is evenly distributed into 6 half-yearly semesters and is widely popular in the country. Since the admission criteria and process differs from college to college.
The minimum required eligibility is the completion of higher secondary schooling (10+2) from a recognized board of education with English and Math as core subjects.
B.Com course is distinct from B.Com (Hons.), as the latter allows specialization in various subjects that students can choose from.
