<p>has anyone taken this before? How hard? Best Book?</p>
<p>I didn’t use a lot of prep books for the World History test. The only book that I read to prepare is Barron. I read it from cover to cover, did all the questions. Then I checked out the CB book and took two official tests.</p>
<p>For me, it’s not difficult, but there’s a lot of trivialities that bothered me really much. If you encounter some questions you don’t know on the test, just use your common sense. It’s okay to have mistakes; you can get almost 12 wrong and still get 800.</p>
