<p>I have AP world history books from barrons and PR. I also have sat subject book from barrons PR and kaplan. Which one should I use? I thought it would be common sense to use barrons subject but everyone is telling me to use AP barrons</p>
<p>I have both the Barron’s subject and AP book. Start with the subject book, and go back and refer to the AP for extra information, if there is any. But the subject book should be sufficient on its own.</p>
