My former roommate currently attends HMS, and I'm not going to lie, when I lived with him, I was impressed in everything he did, very hard worker, and definitely not your average person. OCD/Perfectionist down to maximizing efficiency in everything from room layout to diet, etc.
He had a 3.92+ GPA (more A's than A-'s) at a top university, personally the highest GPA I've seen out of all my friends, had a 37+ MCAT (studied the summer after his sophomore year), and was involved in almost EVERYTHING you could think of (some though not for very long). Honor society, multiple dance teams (captain), crazy research with 5+ pubs (didn't really start until he was an upperclassmen, still don't know how he managed to get so many pubs), hospital volunteering (for a couple quarter), had a lot of friends, everyone loved him, also really big on working out and working hard, probs the most popular guy I knew at my university, partied very hard, and somehow still managed to get good grades, I really don't know how. He had his quirks though, definitely not your average person.
Basically the best of the best.
