I went to Caltech recently, and I feel I should weigh in on this.

The author of the article spends an unfortunate amount of time talking about SAT and AP scores, as if that's all that Tech cares about. Having served on an institute committee to decide the direction of the Admissions office, I can assure you that this simply isn't true. Caltech's sky-high SAT and AP scores aren't an end in and of themselves, they're simply a side-effect. Caltech looks, more than anything else, for a demonstrated passion for math and science. Near-perfect SAT and AP scores are just a check box on the way to demonstrating a true passion and ability for math and science.

And that's really key, because a perfect GPA, SAT & AP scores, and great teacher recommendations isn't enough to get in. There has to be something more. Usually that 'something more' is independent work in a research lab, science competition, personal projects, or somesuch, and so the incoming class at Caltech is never just people who know how to get good grades and do nothing else, but a crowd of voracious achievers, many of whom have spent their lives figuring out how to push themselves harder and faster towards their passions than allotted for by whatever system they were raised in. To characterize them otherwise is a mistake.
