So here's a helpful tip that I posted in another thread recently. I would check AADSAS on November 30th at 11:59pm and for the next couple of hours after that. Schools hand input status updates into the AADSAS system so if your acceptance doesn't appear right away, it doesn't hurt to wait a couple of hours.
Also for schools that send acceptances by snail mail: Some schools will mail out your acceptance a couple of days in advance (anticipating it to arrive on December 1st). But it actually arrives one or two days sooner.
😉
So if you really think about it, many of your acceptance letters are already circulating in the postal service system right now!
