Hello,
You can only start pursuing CFA  if you are a graduate or in the last year of graduation. So,u can register yourself for CFA Level 1 once you are in 3rd year of BBA programme.

CFA does provide a path-breaking career.You can surely look forward to it if you have an intense interest and zeal in Core Finance and want to make it big in the domain of Investment Banking, Private Equity, Portfolio Management, Asset Management, Valuation,etc.

Thankyou

Hello Nikita. 

No, you can do that do both CFA and bachelor's degree together. While filling the form of CFA, either a candidate should be an undergraduate or he/she should be in the final year. Doing both the things together is not an option.

Hope this helps
