<p>I wouldn’t spend a dime on those courses. None of them will raise your score 400 points. Self study (reviewing the math that’s actually on the SAT, for example) is the best way to go if you’re going to retake the SAT, but have you considered taking the ACT instead? Some people who don’t do well on the SAT do really well on the ACT.</p>
<p>In any case, I agree with mathmom that you should be reading a wide variety of complex literature, including fiction, such as Naomi Novik’s excellent Temeraire series, and the non-fiction magazines she mathmom recommended. Also, drop one of those APs so that you will have time to get a real education!</p>
