Which course will provide better job opportunities in future, B.Com or BBA?

According to best of my knowledge, I would like to suggest you that Both BBA and B.Com have their own merits. It depends entirely on your interest before choosing either of the courses. If making a career in management is your priority then you should go for BBA as it is the foundation of management

If you do BBA, as only mainstream option will be MBA from IIM, it will be targeted by most of the students. But Incase of bcom you can pursue mcom, you can appear for ipcc, MA economics, MA public relations or you may choose any option in master's as per your interest, mba, mca etc. so i think will

Bcom will provide more jobs as after bcom we can do many jobs.
