Hunt’s comments, above, about how the higher your stats the less helpful any “matrix” might be, are right on the mark. And since it is the high-stat schools that engender the most angst, it is those students who are parsing the data to see what their chances are, only to come up against the painful truth that, yes, perhaps students with 800 across the board have a 35% acceptance rate vs. a 15% for 700 scorers–but that still leaves 65% of 800 scorers not admitted. And no matter how you want to frame the decision, the truth is, statistics say you won’t get in. Having a 10% better chance than your friend with the 2250 doesn’t mean anything to your choice of whether or not to apply, in my experience, and if it leaves you thinking that you will get in over him, it’s deceptive.
