<p>I'm using 5 Steps to a 5 right now, because I like its organized plans, and how you can pick which plan you can use. DBQ support seems very weak but question explanations good.</p>
<p>What else are you guys using? I want to buy another book so reviews would be helpful.</p>
<p>Just saw the book recommendation thread, but primary information is from 2005 and sifting through 51 pages doesn’t sound like fun. =P</p>
<p>Are you self-studying? If so, I would try to get your hands on a textbook to get a good grasp of the factual details before hitting the review books.</p>
<p>If not, then five steps should be pretty decent from what I heard. I used Princeton Review to study for the AP exam [took the course] and it was excellent- it got me a 5!</p>
<p>I am actually, shockingly, taking the course. But I have a family history of AP epic failure (despite good to perfect ACT scores). I need all the help I can get. XD</p>
<p>The Earth and Its People 4/e AP edition is the textbook i recommend.</p>
