I read an article today about a student who asked Florida governor Jeb Bush a math question from the Florida Graduation Exam. It turns out Bush couldn't answer it and it was an extremely difficult question. The moral of this story isn't that Bush is stupid, but that perhaps graduation exams are not the best way to determine whether or not a student has mastered enough material to earn a high school diploma.
It is important that high schools prepare students for college, but more importantly they should prepare students for life. Personal finance, taking measurements, figuring out percentages, etc. should be at least as important as being able to figure the angles of a certain triangle.
