Hey,
No when you taken admission for one particular study center you must actually complete your course right there as you have registered yourself in that particular center for BA degree. You might still request them to change your study center but it's not possible to study in other college.
Thank you.

Yes, you can complete the course. IGNOU course is an open course, and can be done from home. So, I think you can join IGNOU for pursuing B.Sc.

Do not drop now after 3 years. It would take 3 more years to complete graduation, no matter what and also nearly same amount of fee. Just endure for 1 more year, then at least you will have a graduation degree in a year rather than 3 years. Also, talk to your friends and parents before making decision. They will suggest you same.

IGNOU does not offer B.Ed in dance. After completing your B.Ed, you can decide on the subject which you want to teach. So, you can opt for dance or any other subject of your interest.
