I am right now pursuing my BBA(3rd yr).aAre there any courses that i can take up before my masters?

U can do computer aided accountancy courses like Tally, First Accountant, etc

Diploma In Computerised Industrial Accounting (DCIA), Part time course- Stock trading Course, PG Diploma in Investment Banking,PG Diploma in Banking & Finance etc you can also opt for CFA or CFP but again indian CFA has less value http://www.fpacademy.in/ or http://www.cbacademy.in/
