Good book?

<p>So I recently found a sat book lying around and so I started using it for studying and I took a practice test and scores fairly decent. Can someone tell me how credible this book is and how close it is to the actual sat? It's a collegeboard sat book for the march 2005 test and beyond with 10 practice tests.</p>

<p>Most likely it’s an old version of the blue book. The tests should still be valid since they changed the format in 2005.</p>
