BBA

Both the fields are incredible in their own way. Being a CA is also an adorable thing because it's considered as one of the toughest exam in India & doing MBA from IIM with good marks means average package of Rs. 1500000. So, it totally depends on you what you want to do otherwise both options are great.

BBA degree has been chosen by science students, but ultimately it depends on your area of interest. If you see it as a viable career option then please opt for the same.

I would advise you to go for B.Com as a lot of career options can be unlocked for you like MBA M.Com, etc. Whereas, BBA is in a way restrictive where you have to do only MBA after that. But, ultimately, it's your choice so choose wisely after asking and enquiring with few other people.

Following are the best options for you:
Acharya Institute
Presidency College
REVA University
