Any tips on how to keep my SAT skills from degrading?

<p>Freshmen year I took some SAT prep classes and ended with a 2000 on their last practice test. This year as a sophomore my PSAT dropped...to an 1800. I know that there is some skepticism over these courses but there is still an obvious drop. I believe it was the gap in between (6 months) and I forgot the concepts.</p>

<p>Could anyone lend me some advice on how to keep my SAT skills sharp? Or how to review the concepts before the actual SAT? (I was thinking of reviewing over a used BB test and thinking about how to do them before the real test)</p>

<p>well personally i feel the PSAT is harder than the SAT, and to stay sharp just continue to take practice tests during that 6 month layoff.</p>
