Fat Head,
first the mcat scores and gpa are the foundation to your application, in general if they are up to par you have a shot, then its everything else on your application that takes you the the next step.
One thing that helps alot is believe it or not sport involvement, alot of medical schools like to know that applicants can say cooperate with people (like you would on a sports team) and your used to relating with peopl (all the social things that go along with it). Medical schools arn't just looking for people who can memorize a text, they want people who posses the character traits of a good doctor on top of the intelligence. Also Volunteering is huge, It shows that your compationant empathetic etc...... Great traits for a doctor to posses. Not to mention if you do both of the things i mention above it shows you can multitask which is key to becoming a good physician. On the admisiins essays dont ramble on about how being a doctor is all youve wanted to do since you were a kid, be specific if you have a personal experience (private or not) that drove you to this career say it. My father and mother had cancer, i talked about it in my essay, then during my interview the comitte specifically brought that up, personal stories like that make lasting impressions. Finally during the interview itself dont search for the yearbook answer on everyquestion they ask. The point of the interview is for the committe to get to know you, not listen to all the bull**** you memorized before hand. Sure do your homework and have alot of info in your head, but be honest and confident in the interview, say whats really on your mind, if you make it to this point they're trying to talk you into going to their school just as much as your trying to get it.... Anyways thats a few things that i found helped me...
good luck to people still waiting, and good luck next year to anyone re applying!
