Any point in getting separate books for AP and SAT Bio?

<p>I already have cliff's and barron's prep books for AP biology. Is there any value in going out and getting prep books for the Biology subject test? I heard Barron's and PR are good for the SAT subject test, but thought that getting 2 Barron's books for the same subject would be kind of pointless...</p>

<p>Thanks</p>

<p>Hmm... I would say yes because it specifically points out the most commonly seen things. =)</p>

<p>Get Princeton</p>

<p>Ok, that sounds fair... at least I won't feel weird over having two barron's books...</p>
