I'm scheduling my MMI now and it's kinda weird, there are only like 5 dates with availabilities for the rest of the year, but there are 2-3 clustered availabilities on each day (i.e. 1:30pm, 2:15pm, 3pm). Given these clusters it seems unlikely that some some days already completely filled while others have many slots? I'm thinking that they have only 5 interview dates with multiple interviews going on during each time slot. Basically, based on what I'm seeing, I'm guessing there are still plenty of spots.
Either way, the earliest I'm seeing is Oct. 28th! Latest is Dec. 7th, and they DO NOT have rolling admissions so they make all their decisions after all of the Fall interviews are done (late December) and then they repeat for the Spring....I called Dr. Copeland today to confirm this.
Also I'm a reapplicant so I understand how much worse this process is the second time. No one should spend 2 years being judged like this. Good Luck!
