Last year I called LECOM up every 3-4 weeks for updates after I was placed on their waitlist. They also told me they accept 50/50 off the waitlist, placing approximately 150 on their waitlist and accepting 70 by the end of the application cycle. What they don't tell you is with people constantly removing their name off the waitlist, they are constantly adding people to the waitlist to stay at 150 people on their waitlist, so the chances really aren't 50/50 as potentially more qualified candidates enter the waitlist pool. They do not rank applicants on the waitlist, rather they continously re-review applicants. Just take what admissions tells you about the waitlist with a grain of salt :\
