If you can share you application experience to OMFS, than that will wonderful! Your Part 1 score is very impressive, unless you apply to big time MD programs, your undergraduate GPA may be overlooked. Also, I know Columbia does not ranking, but I thought you've mentioned that you're somewhere in the top 25-30% of your class?
BTW, do you mind sharing your undergraduate cumulative GPA, if you don't want to share publically, feel free to PM me. I'm interested because since I'm applying to OMFS for the 2006 and I have a very substandard undergrad GPA.
