A link from Better And Better sent me to find out if I got the taxpayer's money's worth out of my dimly-remembered high school education. You be the judge:
I must've dropped a question or two (there has to be weighting; can't be a straight percentage if I got 91% and there were 18 questions.) If I dropped one, I'd guess it to be the one about the area of a triangle. Mathematics and geometry were never my strong suits; I vaguely remember how to find the length of the hypothenuse (which is a Greek word meaning "the upstairs bathroom is occupied"), but the area? I'm throwing darts at the answers.
The only other one I could possibly have missed is #10, the one about the three largest religions. If the test writer claims I answered any of the others incorrectly, then the test writer is wrong. ;)
