<p>Are either of these books truly helpful? What prep guide would you reccomend???</p>
<p>Err, I don't think they're helpful. Just get the blue book, take tests, and then study said tests.</p>
<p>I got and used the Barrons 2400 for the most part. It seemed to not really help me at all, but at the same time I was out very late the night before and that could also be the reason I didn't do well (1970). I also scored about a 195 on my PSAT (w/o prep) so you make your own judgement. I thought it was helpful but in reality it didn't help my actual scores.</p>
<p>i used Kaplan 2400 and went from 2120 to 2300....i used it only for CR though, and went from 660-700. i also took all the practice tests from the blue book, which i think made the most difference</p>
