<p>My son liked the Princeton “Cracking the…” series. He pretty much self-studied for the Chemistry SAT II the year before he took AP Chem and did well on it using the Princeton book (with help from a friendly Chem teacher at school when he got stuck). He had taken honors Chem in sophomore year but it was poorly taught and he decided not to take the SAT II, but then found he needed it for one of the schools he wanted to apply to and felt he was almost starting from scratch when he studied for the SAT II in Junior year. So, he thought the book was pretty useful. I forget what he got on it but it was over 700. </p>
<p>I don’t think he bought a SAT II prep book for Biology since he was in AP bio at the time and didn’t prep separately for the SAT II in that. Not sure if he bought a book for Math or not but if so it would have also been the Princeton one.</p>
