Overseas I used to go to school from 8am to 1pm with 40min classes(and I received much better education). In US I had to sit for over an hour per classs and until 4-5pm. Is this any wonder that kids can't sit from 8 to 4 with very small brakes in between? I didnt learn much in American HS, it was torture most of the day. All I wanted to do was to get my work done and gtfo /go home, but that system made it very difficult to do. In fact, I didnt care much for school as a result.
