Which study guide?

<p>I’ve got the following guides </p>

<li>2006 PR sat </li>
<li>2006 Barrons sat</li>
<li>Barrons 2400 sat </li>
<li>Blue book </li>
</ol>

<p>I’ve taken the sat twice and am retaking this June, I plan on redoing some of the blue book tests. </p>

<p>I wish to know, from those who’ve had experience, which study guide is the best in the following catagories. </p>

<p>-Essay/Grammar
-Reading
-Efficiency at learning
-Accuracy of tests (not including blue book) </p>

<p>Thanks</p>

<p>Efficiency at learning? What do you mean?</p>

<p>The PR book has the best tests outside of the CB tests.</p>

<p>the one that gives the biggest benefits for the least cost (time/effort)</p>
