Hello Akanksha.

No, Indian Institute of Management  (IIM) Bangalore does not offer a BBA course. IIM Bangalore offers only postgraduate degrees and diplomas and no undergraduate course like BBA is offered. In fact, none of the IIMs in India offer BBA course. But IIM Indore offers 5 year IPM programme which is BA( foundation in management ) + MBA in which you can take admission directly after class 12th.
