But the fact that you even know the SAT scores of people around you is weird. I'm not in the US, so I haven't done SAT's, but I couldn't tell you a single test score or grade average of anyone I know or went to school with. Why? Because it's just not interesting.
That's especially true as the SATs are not very challenging... Anyone with a decent math knowledge can get a 800 on that part. There's no way to discriminate the very good students from the truly exceptional ones.
Also your high school level isn't very representative of your overall intelligence.
Sorry but that is flat out wrong. The SAT math and verbal sections are not about knowledge but about reasoning abilities. In fact, the "knowledge" (rules etc.) is given right along with the questions. Not anyone can get 800, only 1% of all test takers manage to get 770 or higher on the Math section. The reading section is even more difficult, the scores of the top 1% start at 760 there.
