I believe that the waitlist goes out once all spots are filled. UMMS can't over accept, meaning they may only have 125 acceptances out at any given time. They are pretty consistent in their timing from year to year. Look at the prior year's threads and you can guage when the WL goes out. I don't remember off hand. Just because you haven't heard yet does not mean you won't get accepted either outright or off the WL. Stay strong.
