AMSCO’s US History book is awesome… [Amazon.com:</a> United States History: Preparing for the Advanced Placement Examination (9781567656602): John J. Newman, John M. Schmalbach: Books](<a href=“http://www.amazon.com/United-States-History-Preparing-Examination/dp/1567656609/ref=sr_1_1?ie=UTF8&qid=1322972752&sr=8-1]Amazon.com:”>http://www.amazon.com/United-States-History-Preparing-Examination/dp/1567656609/ref=sr_1_1?ie=UTF8&qid=1322972752&sr=8-1)</p>

Getting a PR book is also recommended for when the exam rolls around</p>

Thanks…I don’t have a computer to buy it from the internet plus my mom wouldn’t let me…hopefully my library has it,does the same company have books on ap calculus ab?</p>
