Sommerswerd asked me to change this
I am speaking from firsthand experience in dealings with Chinese colleagues. Even in 2nd or 3rd year math or science courses, they often tell me that the stuff were already taught in high school. And of course, my parents are teachers in Hong Kong. They often commented that the high school curriculum in Ontario is very lax (as do many of their friends who are also ex-teachers).
And since you'd like to talk about the Chinese cooking numbers up, let me remind you that grade inflation is a serious problem that plagues the top institutes in USA. This includes even Harvard, Princeton, and Yale.
My aunt is a high school math teacher (grades 10-12, I believe) and I've heard from her many times how idiotic her students are and how easy the material is.
I'm not surprised. This might sound like a cliche (or maybe not?), but I sucked at math in Poland. I found it tough. I moved to Germany and all of a sudden I was awesome at it. The material was just a lot easier.
Then I moved to Canada and ended up excelling at math.. quite a bit. I ended up going into a math/cs degree in University because I was just so good at math.
But was it me? Nope, the level just dropped so much when I moved to Germany and then Canada that I found a lot of it laughably easy. A walk in the park. Things only started getting intense when I got into University.
Canadian students have got it easy.
