Referring back to the article which discusses our standing in comparison to other countries; ds has friends from China and Korea at his school so he is quite aware of how different their prior math education was in comparison to his own. He tells me that his Chinese friends had been instructed through at least precalculus by end of middle school. Additionally, they learned what we consider �extra math� such as logic and problem solving as part of their normal curriculum and they are really, really good at it!
