The point is:
Some dudes are fat dumb and happy with their 95% academic average if it's "pretty close" to the top guy. It doesn't matter if 95% is a good score or a bad score relative to 50 years of UPT students. It only matters where it ranks in YOUR class. If the top guy has a 97%, most of the class has a 96%, and you have a 95%, then you get the min points. You don't get 2 points less than the top guy. There is a curve.
Brabus is spot on about not worrying about it and about prioritizing the more important things like checkrides.
But every dude comes home dead tired one night with a test/EPQ the next day and has to make a choice...watch Seinfeld reruns and unwind or study a little extra for that test. Maybe a couple questions over the course of a thousand won't make a difference. Maybe it will. I've said it before: I watched a kid miss a T-38 by one spot. When we looked at the numbers, if he had gotten THREE QUESTIONS more correct, he would have gotten that slot. Do you think if he knew that going in he might have studied a little bit more? You bet.
