<p>AP US Government and Politics Crash Course - 179 pages/$9.56 on Amazon</p>
<p>The Crash Course book is direct, well-organized and solely focused on key information that will translate into points.</p>
<p>As noted above, 25 of the 60 multiple-choice questions on the 2009 exam tested key concepts. Chapter 2 in Crash Course contains a glossary of 88 key terms organized by topic. Anyone who has studied AP US Government knows that 88 terms is actually a relatively small number of those in a typical AP Government text. The Crash Course glossary produced 21 hits out of 25 questions. (The other 4 terms were defined elsewhere in the book). That is both amazing and efficient. So if you reviewed the 88 terms in the Crash Course Key Terms chapter you could earn 21 of the 91 points you need for a 5.</p>
