<p>Princeton review or Kaplan for chemistry? Which one is more easy to understand? Which one covers more topics?</p>
<p>I personally don’t like Kaplan that much due to the vast number of errors on their AP Calculus tests. I’m not saying Kaplan AP Chemistry is worse, but you may want to be cautious.</p>
<p>I am also waiting for the answer.</p>
<p>Princeton Review hands down.</p>
<p>Raised from 710 to 780 after heavy studying.</p>
<p>Now I use Princeton Review for every subject. Haha.</p>
