Waitlist questions should generally be put on the wait-list thread, ideally after you have read it. Start here. This response pretty much covers it. Current parents and students have no special insight.
Offtopic conversations between members should go on the freakout thread, not here. I’ve deleted a few posts.
The general answer is yes, it is possible. It is also very unlikely. Accept a wait-list spot, but also accept a a spot to a school that admitted you, if applicable. Love the school that loves you back.
