Query: this is probably the worst review book I ever used

I started studying for the SAT with this book. I immediately didn't like the whole discussion about Joe Bloggs and the idea that the people making up the test are trying to trick you on every problem. But I still used the book for a while. A few of the strategies and tactics were OK, but most of them were either stupid or not very well explained. I finally gave up on the book and tried two others: Gruber and Barron's. Both were much better than Princeton---Barron's was clearly the best. I learned much more from that book than the others.
