Hello Roopak

As course BBA is much better than BMS but there are others factors as well.

BMS is comparitively a new course and is meant for people from diverse educational backgrounds.
Whereas, BBA is more reputed and is meant for people mainly from commerce background.

The curriculum of BBA is more rigorous and consists of various industry relevent courses which will help you find a good job.

On the other hand, BMS consists of various diverse subjects, which will give you good exposure but it wouldnt provide you in depth knowledge.

Also, if you're planning to an MBA after your graduation, then BBA would be the better option, no second thoughts about it !

Best of luck
