It seems, according to NickNaylor's previous post, that just about everyone who was continued in the cycle is offered a waitlist spot. This is just conjecture, but I think Pritzker fills the class from the continued list after the April 30th deadline (they offer however many spots they need to reach 88 members). Then everyone else who is still on the continued list gets dumped into the waitlist, which is used to fill the few seats that open if currently accepted students get off the waitlist (and decide to matriculate) elsewhere. This is just my impression though, I could be wrong!
I'm guessing they had a really good initial yield this year because they formed the waitlist relatively early compared to previous cycles. Regardless, we'll see what happens! Pritzker would be a great option to have, but I'm definitely excited and happy with my current decision, and many of you should be too 🙂
