Even further off-topic, but I've heard both tests are utterly meaningless if you manage to get into a good community college before uni, one with a Guaranteed Admissions Program with your uni of choice.
Seriously, though, I got fucking sick of standardized tests by the time I got outta school. I had 3 standardized tests I took thru school, that I can remember: Stanford 9, ACTAAP, and ... somethin with the name of a state, I think it was Iowa, or somethin. Its hard to remember because they're all the fucking same fucking thing. Also, bloody stupid easy, if you managed to memorize a few key things, so its entire purpose (gauging how well a school was doing, academically) was thrown out the window because it wasn't an actual test of what you'd learned, simply what you could memorize.
