You will have to drop out from the college in which you are persuing BSc.Get the proper documents from tbe college legally and drop it.Now eligibility fro BBA requires 50%  marks in any stream in class 12 frok recognised university.Though various colleges cutoof marks are high like 75% and some of them also conduct entrance exam.So, you will have to go thought that in order to get into BBA college.

Goodluck
