Hello,
Sastra university takes admission through two process-
JEE Mains (70% seats)
10+2 merit basis (30% seats)
You have to fill the application form which includes both her Mains score and 10+2 marks or percentage. Accordingly, you will be allotted the seat. No need to fill separate form for JEE and 10+2 merit basis allotment.

Acharya Nagarjuna University - [ANU], GUNTUR, SRM, GITAM and VIT are some of the best colleges for BBA.

Yes, you can, if you fulfill the requirements for the free seat. But, as according to my knowledge there is fee waiver seat in which only tuition fees is waived off.
