B.Com

Hello Sonali,
List of Colleges in Mumbai for pursuing B.Com with economics:-
Jai Hind College
BNN College, Thane
Vishwasattya Arts and Commerce College

You can take admission in both but it's not possible to get admission in good colleges with 45% but one thing is that if you want to do business, you should go for BBA stream or else, have an option of B.Com.

Dear,
As per your query, you can think of these fields:
LLB
MBA-(finance, international business, marketing, HR, media management)
Advertising
Journalism
Development studies
Social Work
International relations
Public Policy
Psychology
MCA (If you had Maths upto class 12th)
PR and event management
All the best.

Well, the forms for SYMBIOSIS are already out and the last date for submission of forms was 13 April 2017. So, now, you need to apply to some other university.

Christ University is one of the best universities in Karnataka with all facilities. For more information, you can visit the campus.

Good evening,
Go for LLB once you complete CS, it would be difficult to balance the two at a time, or you can rather go for M.Com and then opt for LLB.
Thanks and all the best.
