You mean like the standard "thanks for submitting your application email" or actually heard some news back from?! I haven't heard anything from anywhere except the confirmation emails that say they got my application and it's under review haha...
As far as USC goes, I'm pretty sure they are one of the schools that gets back to candidates pretty late aka last week in Feb/ early March. Also, they definitely respond in waves. That's really all I know about the acceptance process at USC.
altikr25, unfortunately I know nothing about UPenn... I'm feeling that we should be hearing back from programs that interview soon though. I'm in the same boat as you, past boards show that some applicants had interviews scheduled with Albany the first week in Feb so hopefully we will hear something by next week!
