BBA

IIM-A does not offer BBA course, you may pursue BBA from another college and then apply for MBA.

It depends on the college. If it is top IIM then it will be around 20 lakhs. Baby IIM will be around 15 lakhs. For IITs and NITs it will be within 3-4 lakhs
MBA life will be very different from the UG session. It academics will be more practical than studying theory. MBA will mould ourselves for the outside world.

Hi,
Yes, of course you could get admission in any college for BMS or B.Com. Every college has some quota reserved for students, try to contact the college body.

Hello,
For getting admitted into any kind of good college you will have to pass through an entrance examination
I will suggest you to fill up the form for colleges still you have some time for some colleges apply for DU and others.

I will suggest you to choose the course according to your interest as both BBA and BCA are very different from each other. One is technical and the other is professional.
But according to me I will suggest you to choose BBA.
