<p>Chemistry is not a subject you should study with a prep book - far too much information to get a good understanding. I really recommend buying a chemistry textbook (you can get a used one for really cheap) and read/do problems for the chapters that are covered in the curriculum. It will be far more insightful and you’ll get a great foundation. Here’s the book I recommend:</p>
<p>[Amazon.com:</a> Chemical Principles: The Quest for Insight (9781429209656): Peter Atkins, Loretta Jones: Books](<a href=“http://www.amazon.com/Chemical-Principles-Insight-Peter-Atkins/dp/1429209658/ref=sr_1_1?ie=UTF8&s=books&qid=1278727119&sr=8-1]Amazon.com:”>http://www.amazon.com/Chemical-Principles-Insight-Peter-Atkins/dp/1429209658/ref=sr_1_1?ie=UTF8&s=books&qid=1278727119&sr=8-1)</p>
<p>This might be a little more than AP material, but the more the better.</p>
