FYI, I went to this high-school too, and it's a science and tech magnet school. Granted the liberal arts there are a notch above average, but it wasn't what the school was focused on, and from my experience, the history class was not on the level of a good AP class at other schools (though there certainly are plenty of bad AP classes out there).

I don't think this contradicts Matt's point, since the history classes he took were likely better than average for the US, but I feel he was overstating the quality of them.
