It turned out that the kids who want to do well within their high school had a better chance of doing well in college, even if they had to take catch-up courses or get peer tutoring.
Absolutely not, because being put in the remedial class was "tracking" so there could be no separating kids by ability. My daughter was sent to the library about every other day because she got her work done the first day and it was supposed to take two or three.
I am sympathetic to the idea that when a student is a little behind at one point doesn't mean that they always will be. Maybe things are going on at home, maybe they don't have a home, etc.
But our local school system insists on treating them all the same, regardless of their abilities.
My advice to my kids was to take any AP class that you could. It would be harder but you'd be in a class where the other students wanted to learn and almost always the teacher wanted to teach.
