What APWH review book is the best?

<p>I've searched online and have read that Cracking the AP World History Exam 2015 and 5 Steps to a 5 are both very good review books. However, I am looking for a book that helps explain both the multiple choice and essay questions. My AP teacher isn't doing an amazing job so far teaching the class, so I will almost be self- studying.</p>

<p>Thanks so much! I appreciate all the help.</p>

<p>P.S. I haven't included the APWH book by Barron's, since I have heard that it includes a lot of excess information. I am looking for a book that rounds up the information, so that I can understand the overall concepts of each topic.
Once again, thanks a lot!</p>
