Nice try...I don't have to ask my MD what his MCAT scores were because I know they were above an 18 for him to get into medical school in the first place. If you do not have the critical thinking skills to do better than that on the MCAT, then you do not have the critical thinking skills to do well in a clinical setting. Granted you have two-three years to improve (since generally the first two years are in the classroom and lab), but there is no way an individual who did that bad on the MCAT can take a problem, possibly something they've never seen or heard of, exrapulate the relevant information, and apply what they do know to provide treatment. That's what the MCAT is...its not some standardized test to see how much science you've learned. Its asking you to understand basic physics, chem, ochem, biochem, and biology and be apply to apply these principles to questions based on passages (often time mock experiments) you've never seen before. Oh and you have to understand a little bit of english, any individual who has been accepted into college should be able to pull an 8 on the verbal section IMO.
I'm not trying to sound mean, this is just a reality. Not everyone has the ability to be a Dr. There are plenty of other health-related professions that you may excell at. I have a buddy who is amazing with people, but isn't great in the classroom and would likely score about a 20 on the MCAT no matter how much he studied. However, he is applying to PA school. There is no doubt in my mind that he will be an excellent PA and if I were ever in a position to hire one, I'd get him to sign on the spot. I could trust that he could handle his cases and he would never lose a patient due to poor bedside manner. In fact, I wouldn't be surprised if all of the older women that came into my office would refer their friends just because of him.
