<p>Hello, </p>
<p>I recently found out that the College Board will be shipping the third edition of their official study guide (commonly known as the "Blue Book") on 08/13/2013. However, since there is close to two months until then, i don't want to just wait until then. What would you say is the best study guide (other than college board's blue book 2nd edition) in terms of practice, tests, and most importantly explanations.</p>
<p>Thanks!</p>
