How reliable is this book at increasing scores?

Test Preparation
1

<p>I need prep books focused on critical reading and writing (either in one book together or separate).</p>

<p>this is my shopping list so far:
The Official SAT Study Guide: 2nd Edition by College Board (Editor)</p>

<p>The Real ACT Prep Guide: The Only Official Prep Guide From The Makers Of The ACT by ACT Staff</p>

<h1>Cracking the ACT, 2010 Edition by Princeton Review</h1>

<p>anything else I should get?</p>

<p>My main focus is the SAT </p>

<p>I heard Barron's is good and i came across this book:</p>

<p>Critical</a> Reading Workbook for the SAT, Sharon Weiner Green, Book - Barnes & Noble</p>

<p>how is that book?</p>

<p>I bought the Barron’s CR Workbook. It had test-worthy passages and questions, though I never really used it.</p>

<p>I recommend buying it, if the Blue Book is not enough practice.</p>
