"That was less true when Gates took it than it is now. Now, scores are "recentered", so you can get a couple questions wrong and still get a perfect 800."

Not true, for the math anyway. You can get a few wrong on the verbal section and still get an 800, and don't ask me how the writing works.

In any case, the effects of the 1994 recentering on higher-end scores (for whatever they're worth) are greatly exaggerated.
