Good Grief! Does that ever speak to a point that I have been on a ‘soap box’ about for about thirty years. I have opposed the so-called “AP-Calculus” in U.S. secondary schools. My opposition has nothing to do with a student’s ability to learn the material, but rather it has to do with the ability of availability of the teachers. Now I speak from a great deal of experience. I have taught in many “teacher training courses for AP-calculus sessions”. But I gave up. Only 1 in 20 were able to really grasp the basic notation of calculus. What an absolute shame that someone is allowed to do the Calculus AB course and complete it without knowing about a unit digit.

I happen to know what MathStud28 is talking about. When I was in younger grades I used to help out the 12th graders with their Calculus. I was able to do the problems, usually easily, the only problem I had sometimes was to understand some terms which they used in the problems. Because when you study math by yourself there are just some words you never seen before.
