Have BB first ed, is second ed worth getting?

<p>Question in title. Also, where can I find explanation to the answers in BB first ed?</p>

<p>Yes. The 2nd one has 3 more practice tests.</p>

<p>well, on the CB’s My Organizer, you can enter in the answers of both 1st ed and 2nd ed. I believe then you get the explanations.</p>

<p>I don’t know for sure though.</p>
