<p>I finished the 1st Edition of the Blue Book, and was considering to buy the 2nd Edition. However, I heared that the 2nd Edition only has about 3 or 4 new tests. So would it be worth spending money on it? Otherwise, what other books should I use? </p>
<p>Also, I did well for the most part of the Blue Book, but did surprisingly awful for the Section 9 CR. Were there perhaps some wrong answers published in there, because some of the correct answers made absolutely no sense to me. </p>
<p>Thank you.</p>
