I had an interview at PENN in October, but I haven't got an acceptance packet yet. I guess I am not accepted at this point. Does anyone know whether they send only acceptance packets on Dec 1? Since they do not use any electronical ways to contact students, I am a bit frustrate what my status is. Should I just wait or call them if I am on the waitlist? During interview, I was told that they do not want us to call them though.
