before the curves were adjusted to make 45 impossible. You have to look at it from the med school adcom perspective-if 45 is actually achievable, then they can't compare applicants. I took it in 2004 and they did tell us that 43 was the highest score that year.
Anyway, I agree with the above people that high scores are mostly based on luck. In my five Kaplan practice exams, my highest cumulative score was 34, and I never got above 12 in ANYTHING. On the real MCAT day, I just lucked out. My Bio section had only one Orgo passage, and it was one of those where you could answer the questions just by reading the passage. I talked to other people after the test who had up to HALF their questions on Organic. So I ended up with Physics-11 (reflecting my actual natural abilities), Bio-13 (reflecting graduate work in Biology and no background knowledge of Organic), and Verbal-14. Not sure what happened on Verbal, I scored 12's on all five Kaplan practices, so I didn't do any prep for it at all. It's probably the same as Orgo-the other people taking the test had harder passages than I did.
Aside from dumb luck, I just woke up feeling really pumped on MCAT day. I felt like my chance had finally come. I listened to happy, energetic, inspirational music during all the breaks, ate a well-planned lunch, stayed positive and confident, talked to NO ONE but my family, and re-committed my life to Jesus about a dozen times that day.
So just remember-your high score can only happen if lots of other people get crappy scores!
