How rare are triple 800's on the SAT Math Level 2, Physics, and Chemistry Subject Tests?

@marwin100 I am not trying to paint the whole oriental students’ population with one black brush stroke. I have worked with students from China with high work ethics standards; I have also encountered Chinese students who would not consider cheating beneath them. Same is true about American students.
What I am talking about is how wide spread gaming the SAT and other tests is in China and South Korea and how that leads to an overabundance of high scorers.
