OK guys, I have been in the SAT teaching business for years.
I just want everyone to know that the astronomical scores on the SAT of Asian Americans, specifically Koreans and Chinese students have forced the college board to change the SAT. Much like when the NBA revised its rules because Shaq was too dominating.
The grammar section being added as 1/3 of the new SAT in 2006 is largely a result of the poor grammar skills of Asian students. Back in 1994, the TSWE was the grammar test on the SAT, and schools did not look at it at all. Now it is 1/3 of the SAT test.
The SAT was also recentered in 1995 because of the extremely high scores of Asian SAT takers. The reason they recentered was to lower the ceiling of the SAT, so that the differentiation of the upper 1% of the population in SAT could be more easily confused with the upper 5% of the SAT test takers.
In other words, Asian students are scoring too well, and they are changing the rules of the game, just like the NBA did with Shaq. This has all been confirmed by the founder of an extremely well respected SAT education institute.
