This book does not include anything new in the way of advice. Its formatting is not as accessible as some of the other options, and a student working on his or her own may find it intimidating. However, it does include plenty of great problems. There is an art to writing good SAT-style math questions, and Richard Corn (an SAT tutor in New York) has the technique down. I still prefer Top 50 Skills or PWN the SAT for students working on their own, but if you've worked through those, and you would like some additional targeted practice, this is an excellent option.
