Well, depending on the school, most don’t get off the waitlist.
Any school that is offering merit like that is saying - we need bodies and the sticker price is never paid - our real price is x school minus $24K.
You can look at the common data set section c and see how many got off the WL last year - and tell the school and I’ll look for you.
I find that hard to believe a school would say this though. Are you sure you’re not mis-reading.
