Official Book Question

<p>First off, where do I find answer explanations to the practice test questions in BB? It only gives the answer (A,B,C,D,E). I have the old</a> version</p>

<p>Also, is the new 2009/2010 version of BB different? I got the old BB 2005, the next year I took a SAT class and they gave out "updated" (2006) BB. The questions were exactly the same. Now there's that new Blue/Green book. Are the questions and tests changed or updated (hopefully)?</p>
