"Surprisingly low numbers, considering how many hundreds of students ace their calculus tests in college." I think there's a trend of becoming a better student in college, so I don't find it so surprising to ace calculus in college. myself as a counter example, I was an ace in high school passing 10/12 AP exams, and almost failed out of college--go figure?
