They're going to send out another letter saying that are all spots are filled in a couple weeks. If you're not offered a spot by that time you should contact them and they'll tell you why they waitlisted you.
I have a 3.7 with 86 on Hesi. I thought I did okay in my interview but I'm still really nervous! It seems like less ppl applied this semester since they only had one round of interviews this time.
