Differences in editions?

<p>Are there any significant differences between the 3 Collegeboard Official SAT study guides? I think I have an older one, that says "For the March 2005 Test and Beyond" in the corner, and has "For the New SAT" under the title Study Guide, so I'm guessing its the first edition. Should I get a more updated edition?</p>

<p>I think they're both the same.</p>

<p>Everything is essentially the same, although there might be a few changes.</p>
