Jan 2010 SAT surprises

<p>Whats the best way to handle a 200 point decrease in SAT score? Help-My child went down from 800 to 640 in math-(yikes) 660 to 600 in english and stayed consistent in writing-where do we go from here? We were expecting a better score hes a test taker usually is in the 99th percentile on standardized tests-his GPA is 91 with AP/advanced/honor courses we could be in big trouble any ideas thks</p>
