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</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>
