Yeah if you go through last year's forums, it seems like calls came through pretty much all day long, but everyone got a status change in the evening. Some admitted folks didn't receive any calls at all. No one knows how they prioritize calling list etc. It's mostly the 2nd-year admissions associates who are assigned lists of admits to call... So just hang in there and hope for the best!
How did I ever think I could get any work done today?! Good luck everyone!
