<p>Im looking for a book with a bunch of practice test in them, and I heard about a blue book. But can someone explain what the blue book is.</p>
<p>The Blue Book that everyone has been referring to is the "Official Study Guide for the New SAT" by the College Board (the people who create the SATs). It has 8 REAL practice tests, which are the only kind you should use in your SAT prep.</p>
