What will happen if I’ve been put in the waitlist?
Where? Did you receive an email or letter of explanation with the waitlist notice? If so, what did it say? Did you check the college’s website for waitlist info?
Generally - at colleges - you are offered a place on the waitlist and you can either accept or decline the offer. There is no guarantee you will come off that waitlist, however, and the odds of doing so vary greatly.
What else do you want to know? Your question is unspecific.
In this thread, you are talking about prep schools?
MODERATOR’S NOTE:
Closing thread. We do not deal in hypotheticals, and since your other posts indicated that you have yet to apply anywhere, this question does not pertain to you at this time. In the interim, the below linked thread will tell you just about everything you wanted to know about waitlists.
