DU doesn't offers proper BBA, it offers BBA(FIA) where FIA stands for financial investment Analysis. Secondly, DU offers BMS which is as similar as BBA.

In both the courses admission is granted via entrance exam. You have to clear DU-JAT for admission.

You can get admission in DU even if you are a one year pass-out.You will just have to show transfer certificate and some important documents.

Hope this helps you.
