Remember, GPA and MCAT are mattering less and less. Schools are placing a higher emphasis on your personal statement, secondaries, LORs and your interview (especially MMI).
I am in charge of hiring interns at our office every semester and I can honestly tell you that I won't pick one intern over another because one has a 3.8 and the other has a 3.6. However, I will place a higher emphasis on their personal statement, and their interview. As far as personal statement goes, I will place a preference to students who come from a disadvantaged or unique background. A large percentage of them in (San Joaquin Valley, CA) are African American/Black or Latino/Hispanic/Mexican. There are many poor White and Asian people in our community as well, just a lower percentage of them. For the record, our last two interns have been White (one disadvantaged 4.0, one affluent 3.5). Both had great personal statements and interviewed extremely well.
Finally there is the interview, if you have a 3.9, but are socially awkward, you might not get accepted over the student with a 3.7 who actually has a personality.
My stats: URM, ESL, very disadvantaged both financially and where I grew up. 3.45 28R. 5 LORs, A lot of hospital volunteer experience, many EC and leadership roles including founding two major student groups on campus.
Successful professional career in a non-medical field (unique). A lot of public speaking (came in handy for interviews).
14 Apps, 6 Interviews (1 declined), 1 acceptance (USC), 1 waitlist (UCSD), 3 still waiting.
The point I'm trying to make is that (3.45 28R) is only 7 characters long compared to your whole personal statement, secondaries, LORs and your interview. Medical schools are looking for more than stats. Sorry for the novel, but I can clear anything up if you have any questions.
