Hi Shubham,

BBA and BA are the full time graduation course divided into six semesters. People who are interested in business or management both can opt for BBA.

Fees of diffrent colleges have diffrent diffrent fee structure. It depends on the college to college or university to university. Private college have high fees structure as compared to government. And also you haven't mentioned the College so that we can help you out. Please do mention the college.

Again, if we talk about marks every college or university set up it's own criteria for marks. And they are purely based on Merit.
If you don't have enough marks you can go for the entrance test or You can take Direct Admission. Again it will vary from college to college.

Hope you understand:)
