The whole point of the article is the stress these kids are under because of all that extra work.

It's nice that in your family, this isn't the case. But that does't mean you can extrapolate from there.

I live in an area that's rife with helicopter/lawnmower/tiger parents. I've met them at school, in the gym, at the ice rink, in the park...everywhere. To these parents, A- grades are Cs and Bs are Fs. The cubs spend the summer in the library doing AP coursework. Unless they're too young, in which case they spend the summer in math camp or multi-subject summer school. They have to be on multiple sports teams (often at the same time) and reach a high level or they have failed. The parents crab at the coaches because the kid's scores aren't high enough. For these parental types, anything less than WINNING and getting into a tier one college means failure and letting the parents down.

And so we have a high teen suicide rate and high levels of mental illness.

It's great that your daughter doesn't suffer from this problem, but that doesn't make it any less real for many kids, so please don't be so dismissive by citing your own experience or your own wishes in the face of the demands of 5 AP classes.
