SAT II Subjects Prep Material

<p>I am preparing for the SAT II Subject Tests: Biology E/M and Chemistry during the summer. What is the best prep material for these tests? I already bought the Barrons' books for these tests but I wanna know how relevant are these books. Also, I saw that College Board has a Subject Test book but it will only have 2 tests that are necessary for me. Should I still buy it? Lastly, if anyone has any SAT practice booklet for the subject tests (I already have the 2009-10 edition), please post a link. I'm devoid of subject test prep material. Thanks in advance.</p>

<p>PR + Barrons for Biology is a solid combo. If you're thinking about taking the AP Biology exam, I would buy Cliffs, it will help you immensely for both the AP and the SAT II exam.</p>
