best practice for SAT chem & physics?

<p>hey I am taking the SAT next weekend and I feel like I need a lil more extra practice. Can anyone tell me where I can find useful practice on the net or in a book? Thx</p>

<p>i say barron's. it sure helped me a lot.</p>

<p>What is it?</p>

<p>I used Kaplan for Chemistry. I thought it helped quite a bit.</p>

<p>I like PR for Chem. Definitely helped me.</p>
