Based on all the different books I've seen, admittedly, this really is the best out there. That and the Cliff's study guide. I used this to study for the PPST the night before I took the test and it helped me remember all the materials I had forgotten, some from as long as 10 years ago, when I last took geometry. I took the computerized reading, math, and writing exams, and got above 180 on reading and math(I'm still waiting for my writing scores.)
Unfortunately, that's all it was good for. Being in Pennsylvania and wanting to teach music, I had other subject tests to take, namely the Fundamental Subjects exam and the Music Content Knowledge exam, which weren't even mentioned in this book. The Cliff's study guide was good for the general studies(language arts, math, science, citizenship/social studies) but I still have not found _any_ effective study guide for the music exams.(If anyone out there knows of any, please let me know, just in case I bombed the Music Content Knowledge, or I move to another state and have to take one of the other exams) I was disappointed that this book didn't help me prepare for those exams, but nowhere near as disappointed as I was with my inability to find _any_ test prep materials for the music exams and just fishing through the local public library to find whatever Music Ed textbooks were available.
Granted, not everyone reading this review will be teaching music, but be ye forewarned, that there may be certain tests that you will need to take that this book(nor any other book available) will adequately prepare you for
Anyway, that's my review, and I'm standing by it.
