hello seema,
Congrats on scoring such a great percentage.
Unfortunately, St. Xavier's does not offer BBA as a course but you can apply for other courses of management like Bachelor's of management studies (BMS) or Bachelor's in mass media (BMM). These courses have a good scope. You would have to appear for an entrance exam for the same.
