thanks for the link. I did not like the blue book and bought it for the reason everyone thinks they should: "they make the test, so their study guide must be the best.". The practice tests are obviouslygood to use but did not have adequate explanations of solutions like other books have. I ended up using online resources like
www.khanacademy.org,
www.purplemath.com, etc. I also bought a smaller book from here called "
Secrets to Conquering the SAT" and was very happy with it. I didn't use it, but have heard good things about PWN the SAT also as it specializes in improving math. Overall, it seems like the big books are less and less useful b/c the competition is getting harder and harder and generalized preparation isn't sufficient. I guess it is to say they are helpful to a point, but the days of studying for the SAT and the score you get just 'is what it is" are long gone. Students are willing to do whatever it takes to increase their score even a few points, and the old style of study guides doesn't deliver for that.
