The issue is that when all of these AP/Honors Calc people get to college they don't even make it to Simpson's rule before they're weeded out. That's the problem that most college professors are talking about. How are we creating more and more and more AP/Honors/"Gifted" kids every year, yet the performance of all of these kids when they enter university is abysmal? How is first semester calculus a "weed-out" course when so many of these kids enter with transcripts indicating they've already taken calculus?
I mean, I can totally see where the professors are coming from. We send every state flagship university what all of these very good high schools claim are the cream of the crop, and many of the students sent are just not up to the task. It has to be the school system at some point?
