I am so glad you asked about this flawed. I have also gotten into SAIC for BFA, although I applied to be in the MFA painting and drawing program. They said I would be called a prior degree student, which I assume is the same case as yours?
I am indeed confused about what decisions to make now. I am only turning 23, and don't know if I would earn a lot by taking another 2.5 years in a BFA program. I am sure taking time to make art is perfect, but would I choose to make art in a school environment for another 4.5 years? I am not sure.
