Real AP US history problems

<p>I want to find some real AP US History problems. I ordered the 2001 AP test from college board, but I also want some real CB book that gives more AP Questions based on category and question topic, such as colonial america, world war I, post revolution, etc... I looked into buying the Teacher's Manuel for AP US History, but I don't think that book has any actual questions. Does anyone know what book provides more real AP problems rather than instructions?</p>

<p>Also, I found this great US History quiz site, <a href="http://www.historyteacher.net/USQuizMainPage.htm%5B/url%5D"&gt;http://www.historyteacher.net/USQuizMainPage.htm&lt;/a>, that has over 1200 multiple questions, most from actual AP tests. </p>

<p>My question is, where did the author get all the real AP test problems since the CB only releases a test every 5 years or so, and I asked my teacher if she had any and she said no. So can anyone help?</p>
