Arsenic posted some answers to questions about UMiami from Dr. Hinkley on another thread recently: Basically, Dr. Hinkley said that the "under evaluation" process and duration of time is highly variable. Essentially, three independent reviewers look over your file and give you a numerical score (based on certain number of points for MCAT, GPA, clinical experience, life experience, LOR, etc.). So how long you are "under evaluation" depends on how quickly your 3 file reviewers review your file. I was complete for 4 months, under evaluation for about 2 months (maybe 1.5 months), and then on the ranked list for about a week or so. Dr. Hinkley did say that some people on the ranked list are periodically rejected, so it's not as if everyone gets on the ranked list.

Good Luck
