<p>Actually, I would say that better than 99.5% may be more accurate, as shocking as it may sound. Source: Johns Hopklins CTY says that people who qualify to attend CTY are at the top 0.5% of the population, even though who don't get perfect scores on SAT Math (I'm under the assumption that most of you are qualified to attend CTY). We also must note that National Merit scores reward the top 0.5% of college-bound students, not the entire student-age population. Once you're past SAT Math, there are no tests that you can compare with the general population, for the general population doesn't take those.</p>
