If you read the wording of the waitlisting, it sure sounds as if everyone who is not accepted is waitlisted, now doesnt it?
"You are being offered a place on the wait list. Applicants are placed on the wait list after they interview, and may be offered a spot in the class at any time. Waitlisted applicants may call our office after April 1 to request more information about their relative position on the wait list and the size of the list this year. "
