for years i thought i was stupid for getting a low score.
folks, what it really measures is ignorance. if you never studied something how ya posta get a high score?
so, ya ain't dumb, just unknowledgeable. doesn't mean ya can't learn something.
csap is better, some. it just shows where your knowledge level is, though the 'score' is used to determine whether a school qualifies for more government money.
i had to take accu-placer tests to get into a community college. i didn't fear them 'cause i was told there was no pass/fail, only an assessment of how much i knew of various subjects.

don't get me started about mensa....
