I assumed I hadn't gotten into a couple schools based on dates from last year rej/accepts, and others who have discussed their status from the same school but another dept.

Applied to sculpture:
Columbia
Hunter
USC
UCLA
Columbia just sent me an email for an interview this afternoon. Haven't heard from anyone else yet. Scanning the forums no one has heard back from many of these yet.
