You have me pegged wrong, pal. I have never berated a professor, never approached a professor to bump up a grade. What I have done: I have busted my ass, and my GPA reflects that effort, and it did not keep me from doing any EC or any activity or thoroughly enjoying my college experience.
And do you not see any irony in the fact that per your MDApps, you applied to around 30 med schools and only got into one? You came perilously close to not getting in anywhere, and my guess is that it was your "low" GPA that held you back - a 3.5X is "low" for med school admissions, no matter how you try to spin it (like saying it is "perfectly respectable" - for the general student population, a 3.5x may be perfectly respectable, but for a pre-med, it is low).
Your example is proof of the need to do everything possible to have a higher GPA, not to justify having a lower one. From your own MDApps, you wrote: "I knew my GPA was going to screw me..." and I agree with you (and more importantly, you agree with me).
