The "gravy," as you put it, is being strained already. If you look at the charts on pp. 25-27 of the MSAR, you'll see that about 80% of applicants scoring a 7 on any of the 3 multiple-choice sections of the MCAT are not admitted to any medical school.
BTW, Mr. RedState, has it occurred to you that the MCAT might not actually measure a person's academic ability or potential to succeed in med school? I offer my own experience as an example. I got excellent grades in chemistry and physics at an Ivy League school, yet did poorly (7's) on the PS section of the MCAT twice in a row, due to nerves. (I blew the pacing and didn't finish all the questions.) Five months later, I took the MCAT a third time and got a 12 in that same section; in other words, my score went from 38th percentile to 95th percentile. (BTW, I studied for a month before the retake, and none of it was content, just test-taking strategy and pacing.)
So did I transform from a ****** to a genius in five months? Or could it possibly be that the MCAT doesn't really measure anything, except how good you are at taking the MCAT?
