Some perspective that I think might be useful for people to know about waitlists. Between me and the 2 people I've met at visits so far, we're holding 12 spots at 6 different programs. That means 9 spots total WILL open up, and at some schools it will likely be that everyone accepted goes somewhere else, and every spot opens up.
Idk if anyone else will find this as helpful/enlightening as I have, but I never knew it was like this and thought I would share.
