<p>Hello, I am wondering if the new edition of The Official SAT Subject Tests in Mathematics Levels 1 & 2 Study Guide is worth buying or not. </p>
<p>Besides the updated cover, does it contain any new tests or just the same ones as the old book from 2006? I assume the old edition isn't on Amazon anymore but I can get it from a library.</p>
<p>Thanks!</p>
