I agree with Bostonian.

Almost all kids need a little pushing, gifted kids included. There is nothing inherently wrong about summer school or prep classes.

I do blame the increasing use of extracurricular in college admission. I think the kids are tired not only because they were taking 5 AP classes, they also need to play on a travel sport team or orchestra, and volunteer and be a leader of whatever organizations. They have no unstructured down time.
