<p>I already have the Peterson's online SAT course, but I'll soon be taking the PSAT. Do I need another online course for the PSAT or is everything that I need to know already on my SAT course?</p>
<p>don't take both IF you have sat classes, don't take psat. psat is easier that SAT so psat is covered (even though it doesn't say) in the SAT online course</p>
<p>is peterson good?...i like their math prep book..is their cr good?</p>
