Is there a MCAT score ceiling for each student? If so, what determines the ceiling?
I got asked at one interview if I thought most people could score a 40, and I said no. The main reason is because of how the AAMC curves the test--if the average raw score went up, they would just raise the bar higher and still never let most people score in the 40s when they scaled it. But in addition, most people cannot finish the test in the allotted time and maintain accuracy the way they could if the test were untimed. If people could take as long as they wanted to take the MCAT and the AAMC did not curve the test against other test-takers, then yes, in that case I do think pretty much anyone could score at a 40 level if they really worked at it.
Even with the constraints of the test as administered, I would answer this question by saying, "it depends." Not everyone starts out equally good at taking tests, and not everyone is willing to work equally hard to get better at taking tests. A natural born athlete still has to train hard to win the Olympics. In contrast, a person who starts out without much obvious talent can work hard, make big improvements, and wind up doing very well. On the other hand, not everyone wants or needs to train to the level of Olympic caliber. When I ran my marathons, I was content to just finish; I wasn't looking to have a world-class time. A big part of the reason is that I simply wasn't willing to put in that kind of time and effort. Why should I? Just finishing the marathons was a big enough accomplishment as far as I was concerned. If I had been willing to work harder, I could have certainly improved my time quite a bit more. But I'm not a natural athlete, and I wouldn't stand a chance next to someone who was naturally gifted and also worked equally hard to attain their max.
Here's the thing: many people who are naturally talented coast on that talent and don't work as hard as more average people do. When most of my students (I work for Kaplan) take the diagnostic, they score in the high teens or low twenties. Every so often, I get someone who starts out in the low thirties. Those students often don't have to work very hard; they can ride on their natural test-taking ability. At the same time, some of my students who start out in the twenties also raise their scores up to the thirties by sheer determination and willpower. I've had students finish the entire Kaplan library (which, for those of you who haven't taken the Kaplan course, is absolutely ridiculous in volume).
I wasn't willing or able (timewise) to do that kind of thing, so my studying was more directed. I basically ignored the chemistry altogether and only did the physics and the physiology part of bio. I took five full lengths and no AAMC practice tests (which I don't advise people to do). But, I started out with a 40 on the diagnostic. I had no idea what to make of that. No one in the entire center had ever seen a diagnostic score like that before, including me. I wasn't sure if it was even valid because I don't think these practice tests are very predictive for people who are at either extreme end of the scale. Plus, I had seen the diagnostic before, so I didn't know if I had unconsciously remembered some of the questions or what. In hindsight, I probably could have still done very well without having studied at all, and maybe I would have chosen to devote my time to other (more useful?) things if I had been more confident in my diagnostic. Purposely putting in the time and effort to try to raise my score from a 40 to a 43 is beyond pointless.
Getting back to what I was saying about not needing to be Olympic caliber just to finish a marathon: I want to remind you all again that none of you needs to score a 40 on the MCAT to get into medical school. The vast majority of medical students do *not* have 40+ MCAT scores. Conversely, if you are a person with a 40+ MCAT score who comes across as being arrogant and entitled, medical schools can and will reject you. In addition, once you get here, no one will care about your MCAT score--well, unless you're like me and you teach premed MCAT courses. To be honest, though, I think that my having a PhD impresses the students more than my MCAT score does. I'm not even sure if most of them know how I scored on the MCAT. My last few classes have been exceedingly polite; since no one has asked me, I haven't told them.
