Hello, Few Universities offers BBA without Maths but if you want to go for Delhi University. No, you cannot pursue BBA from Delhi University or DU without Maths in class 12th. It is compulsory to have Maths as the main subject in your class 12th. Courses such as BBE, BMS, BFIA are offered by the Delhi University. Admission to these courses is through a centralised test known as 'Joint Admission Test' (JAT). .

With this percentile, it would be difficult to get admission in this college.

According to me, you should do MBA in marketing that will be a better career for you.
