Which cource is best and after completing in which cource get high salary package. bba(FIA) or BMS please reply please
BMS which is bachelor in management studies is an emerging course which colleges like St Xavier's (Kolkata) and other colleges are offering , you can opt for that if you wish to pursue pure management.
Also as far as you are concerned with high salary package, doing CFA with your graduation and gaining 2-3 years if work experience after it and opting for MBA (finance) from a well known institution like IIM or narsee monjee Mumbai, can do wonders for your career.
However depending upon your potential in mathematics you can also go for actuaries.
It is a very good combination though.
Good luck!
