How many med students have you talked to have told you to avoid "their" school? These things to avoid always seem to be at "other" schools. Just focus on getting as many acceptances as possible and then choose. No schools are notorious for anything, or you wouldn't have to ask who they are.
Edit: This question really deserved a herp derp, but it's Friday.
Weren't you just asking how to get off a waitlist? If you haven''t been accepted, then don't worry about it. If you had actually interviewed at any of these schools, then you wouldn't have to ask.
For some reason, all of your threads stick out in my mind. Which usually means you are a troll. But in your case, I kind of think there is something else going on with you.
