although not all of these are first time sucess stories, I have a few that show that just 1 or 2 points in that VR score can help, or even if you don't improve on VR, you still can have a good chance. all of these are real people that I know.
1)White male, MD resident, 1st time MCAT=27 with a 7 in VR, 2nd time August MCAT, 30 with a 9 in VR. 5 interviews (incl. Emory and Einstein!), 1 acceptance to the U of Maryland school of medicine (no WL).
2)White male, MA resident, 1st time MCAT VR=7, 2nd time=9 or 10 (unfortunately my memory is poor today). 9 interviews (incl. Rochester, U Mass, and Tufts), 1 acceptance to Tufts (off the WL).
3)White male, CT resident who grew up and went to school in Iowa. did not apply to enough schools the first time he applied. 1st MCAT=29 w/ 8 VR, 2nd MCAT, 31 w/the very same 8 VR. Accepted to NYMC, Louisville, and U Minn-Twin Cities, 3 waitlists, cancelled/declined about 5 or 6 other interviews after his acceptance to UMN.
4)White female, MD resident, 1st attempt: 26 w/ VR=7. 2nd MCAT, 29 w/9 in VR. 1st application cycle: 1 interview, 0 acceptances. 2nd application cycle: 7 interviews, 2 acceptances.
5)Middle Eastern/Arab-American male, TX/LA resident, 1st MCAT attempt=24 w/6 VR. 2nd attempt=28 w/8 VR. got into Tufts the first try. 3 other interviews and the only reason he didn't get more was b/c he was too late for the TX schools to interview him.
so as you can see, the VR score is NOT the whole application. also, though I don't know all of my classmates' scores, I do know that many people had <30 MCAT and that one guy from Yale with a 34 got in off the waitlist later than I did. the process makes no sense, but it all matters not once you are in med school! good luck!
