Hello Aspirant

I hope you are doing good . With reference to your query , I would like to suggest you that persuing bba+mba course would be a better option because after completion of bba in integrated course then at mba time subjects are not repeated which are studied eariler in  bba , you will get more priority in  your college since you have done bba from that college though it doesnt affects a lot but it does  . Whereas doing mba after ba , you need to give separate exam like cat ,xat to take admission ,if by any chance you not able to crack top college then their will  be a problem and you have to study subjects of bba too

Hope you found this answer helpful. Good luck for your future
