<p>Holy ****. These questions are hard as hell. I took their dianostic test and found the questions to be way harder than the actual SAT. But I guess once I read the lessons thoroughly I can obtain some good strong knowledge since these lessons are preparing me for their very difficult tests.</p>
<p>Im using Barron's How to Prepare for the SAT 2008</p>
<p>The reading and writing sections of the Barron's books don't seem that much harder to me. The math, however, is a lot more difficult. I don't know if mastering Barron's math would be all that helpful, because I'm not even sure if it tests the same stuff as the SAT. It would be like studying the content of the Math IIC exam just for the regular SAT. Except not that extreme, but you get the point.</p>
