The Official ACT "Red Book"

<p>I'm looking to prepare for the ACT in September and, of course, would like to begin my preparation with the book endorsed by the company itself.</p>

<p>However, I'm experiencing some confusion in purchasing the guide, and I'd like to ask a few questions:</p>

<li>Is it only necessary to buy the newest version of the prep book?</li>
<li>Are the tests included in one version necessary the same as are included in another? (Pretty much answers #1, I know)</li>
<li>How many versions are there? I'm looking at amazon, as I don't have much money to spend, and I only see two released and another coming out in October (of the most recent format).</li>

<p>I believe they carry the same tests, so you're better off just buying one.</p>

<p>Also, you should probably study from another guide first and then do the practice tests from the red book since there's only three of them.</p>
