Real SAT 2's by CollegeBoard?

<p>So I was derping around an archive I found of the Collegeboard Website… </p>

<p>and I found this:</p>

<p>[Amazon.com:</a> Real SAT II: Subject Tests: 2nd Edition (9780874477030): The College Board: Books](<a href=“http://www.amazon.com/Real-SAT-II-Subject-Edition/dp/0874477034]Amazon.com:”>http://www.amazon.com/Real-SAT-II-Subject-Edition/dp/0874477034)</p>

<p>Does anyone know if the tests in the book are different than the tests in the current Official Study Guide? Because this book could be very useful…</p>
