<p>So, I've done all the practice tests in the Blue Book, and so now I'm using the PR 11 Practice Tests book. However, I've noticed that I'm getting SO MUCH more wrong on the CR in that book than in the Blue Book, which worries me. Is this normal or is it just me?</p>
<p>And in general, which SAT Prep books are easier, harder, or almost the same as the real SAT? Thanks!</p>
