No the point is that some people can't change their past. But what they can do is do everything to rectify the mistakes of their youthful past and do everything in their living power to increase their chances of acceptance.
And the point is that the MCAT carries slightly bit more weight then GPA.
But for those of you freshmen, of course keeping both high is better. I already stated that above when I said that a 3.8 and 31 MCAT is probably more likely to have an easier time then a 3.0 and 37. But that a 3.8 and 19 will have a much harder time then a 3.2 and 37. Just giving you some perspective.
