Which test prep book is best for the APUSH Exam?

<p>Barron's, Kaplan, The Princeton Review, or, REA's AP US History exam book?</p>

<p>Out of those listed, Princeton Review is the best.</p>

<p>REA is considered one of the best. The other is AMSCO.</p>

<p>I have to say AMSCO…</p>

<p>However, REA is quite good as well from what I hear. Kaplan’s… that’s just not an option.</p>

<p>I have the Amsco book already, because my teacher gave everyone one but I have to give it back when the exam is over plus I can’t write in it.</p>
