I agree with Samoa 100%. One can increase one's score with practice, however, the upper limit is not the same for everyone(due to intelligence, critical thinking, reasoning ability, etc). The simple fact is for some of us, it doesn't matter if we have a herculean work ethic, there is a cap for one's MCAT score.
On the other hand, GPA is self-discipline, drive, and work ethic.
I think of it like this, and this is a broad generalization(i admit) but might illustrate my opinion.
A person with a low MCAT and High GPA might be considered a "overachiever". Conversely, a person with high MCAT, and low GPA might be considered "underachievers". Thus, if you have low MCAT and High GPA I would emphasize work ethic on my personal statement(i.e. I will work very hard in med school). However, if you have HIGH MCAT and Low GPA, I would use the motivation card(I am not happy with my UGPA, however I am now motivated to succeed due to (you fill in the blank).
Just my 2 cents.
Good Luck everyone, on your med applications.
