The real tragedy is that this man was able to rise as high as he did, and our current system supports it.
My guess is that the test had a lot of algebra 2 material, which requires some memorization of formulas. It's not hard math, it's just sort of plug and play, but it's hard to remember what to plug the numbers into if you haven't had a recent refresher, or you're not teaching it.
As far as getting a 62% on the reading portion, well that's just pathetic.
For all we know, the reading test was either testing for a different kind of plug-and-play (“the author of the above paragraph is using (a) apostrophe; (b) synechdoche; (c) both; (d) neither”) or is testing mastery of a certain kind of teaching-to-the-test in the guise of “reading comprehension”.
You can't possibly be implying that most people are in their current jobs because of skill or training?! Bwaahaaahaaahaaah! Such naivete! Where have you been hiding?
edit: add link & proper version titles.
It would be a fabulous retort if you were this fellow and you actually did happen to know. "Short or long" would be almost as good a come-back as "African or European" when asked about unladen swallows.
Life lesson: If it sounds too easy for the money he's making, it's probably not.
