from Trevor Packer (top College Board exec for AP) via Twitter: "Are too many students being rushed into calculus? Dr. Bressoud, of our math committee, has this point of view: http://ow.ly/d7UGI "
I don't know why people assume that few failing scores means the course is too restrictive. So long as a senior is taking a calculus-track course, and only a handful of college-bound seniors are abstaining from math, then doesn't that mean the school is, in fact, doing a GOOD job preparing students for college math?
My school district is obsessed with quantity of AP exams, and is pleased with the "urban" campus getting 83% 1's, even when other (state and college) exams certify those students as NOT ready for college math.
