No, BBA is not a tough subject for those who are weak in mathematics. Though there is quantitative mathematics in BBA, it has a lesser weightage. BBA is all about taxation and arithmetic skills, which is quite easy if you put a little effort. If you are really interested in pursuing this course, work harder to score great in maths.

Hope it helps.
