I have scored 40% in HSC. I want to pursue BBA. In which college can I get admission? I want a college located in the Northern region.

Sorry, to say dear, but doing BBA with these academics is not recommended. What you will do with these marks in future. I would suggest you retake class 12th exams and score good marks and then do BBA. Some low-class colleges will give you admission for money but that will not help you.
