I feel the same as everyone. This is my second round of applications (was rejected to 5 schools last year after 1 interview and 1 post-bacc offer), and am hoping for a better time this go round. I feel as though I have matured so much from my first time experience. Anyway, to respond to the question above - I started to receive letters last year by mid-Feb.
I sent apps to:
MFA Painting -
Yale, SAIC, UNC Chapel-Hill, RISD, Wisconsin-Madison, Ohio State, University of Kansas, Cornell, VCU
Wish me luck. I wish you all luck as well!
