I emailed this week and this is what they said: "is it worth calling for an update? even to ask if it’s to ask about getting rejected over accepted? at this point i kind of just need an answer so i can move on to other things
Thank you for reaching out to the Office of Admissions. We appreciate your continued interest in Weill Cornell Medical College (WCMC). WCMC’s waitlist movement can last throughout the summer; as our wait list is not ranked, waitlisted applicants are re-reviewed when openings occur. We are unable to give specific times of when individual applicants will be re-reviewed. You may continue to send any updates or communications about the waitlist to this e-mail address. "
Maybe they'd be willing to provide more information over the phone? But it's hard to say.
