Two or three years ago, as I recall, there was a thread about a guy who had his acceptance rescinded. If my memory serves me correctly, the guy showed up for second look weekend, got totally and outrageously drunk at the main social event, sexually propositioned various women in a crude way, and insulted the Dean of the Med School in question. I don't remember all of the details, but his behavior was pretty far out on the fringe of what is socially acceptable behavior for medical students.
So, don't do this.
I recall another thread about a guy who was accepted to med school in Florida without having taken the MCAT. Apparently, his father was very well connected with the governor of Florida and political influence was exerted to allow this young man to be admitted without taking the MCAT, it caused quite an outcry among faculty, and there was an effort to rescind this kid's acceptance and to oust the Dean of the Med School. I don't remember how it all ended.
Presumably everyone currently on this forum who is holding an acceptance has a valid MCAT score - so I would not worry about the Florida situation. But if you cannot hold your liquour, be careful at Second Look Weekends. Above all, do not insult or sexually proposition the Dean of the Med School.
