Business Management Studies

If you dedicate all your time to it, then it's enough.

I prefer University of Madras because it has good faculty.

Attractive placements & packages are there for MBA in Indo Global, which is the oldest, reputed and leading management college of the region offering different courses since 2003.
It is already ranked 3rd in placements in the region of Punjab, Chandigarh & rest northern India.
All the best.

The hostel fee is same for all the courses in the university. You can check out the latest fees details on the university's official website or you can contact them because the fees changes every year.

No college offers them as an integrated course as both are different. CA requires coaching and giving exams, while BBA is a course in administration.
You can get an option of integrated BBA+MBA in some colleges.

To be very true, there is no chance. Your rank is high dear, as much I know.
There is a chance you may get MBA Insurance, which is taught in Karaikal centre.
