I don't think anything I have said is counter to those observations. I never said that all students of traditional classes are successful. My statement is that almost all students scoring a 5 (which is like 65%70%) on an AP calculus exam are successful. The reason so many students succeed in traditional classes (or any classes for that matter) yet are not actually successful, is grade inflation. It is just not in our nature to fail a student that has worked hard all year. It's easy if they don't show up or goof off the whole year, but we can't do it if they tried all year. I doubt even I could do it. That is why it is so important to me to see comparisons of high performance on comprehensive exams.
