Congrats, you just got on the wait list like a couple days ago too right? Maybe the later you found out about the wait list, the better the position you're in to be accepted? Makes sense if they took too long trying to decide whether you should have been accepted right away or wait listed until another spot opened up, but then they decided to put you on the wait list because they couldn't make you wait any longer. Then all of a sudden a spot opened up for you! Haha all jokes aside, congrats again!
