Dear Rana,
BBA or BA LLB are two different courses in different streams. Therefore it's difficult to compare them.

BA-LLB course combines Bachelor's degree course in Arts with Bachelor's in Law. The syllabus for this program as the name suggests includes enriching curriculum in Art subjects.

BBA is an undergraduate programme which provides advanced knowledge of Management. The programme is specially geared to instill management ethos among the students, so that they are professionally ready to compete in the global business world

I hope this information helps you

All the best
