nothing from umich here, either. i'm in the 'no interview invite, but maybe i was so superior as to not need one' boat.
are they sending notices via email, or are they actually mailing them?
michigan had their interview weekend last week - i'm assuming that not getting an invite is the same as getting rejected, although they may have waitlists or waitlists of waitlists that they put you on. official notice goes out any day now.
no idea on the others.
