Query: In need of serious revision...

I purchased several of the high yield and brs reviews for dental boards. As far as the high yield series goes, this one is by far the worst. Most of what is in this book is really basic info, like stuff you learned in Cell Biology as an undergraduate student. It may get you through the boards, but I really doubt this alone could help achieve a high score. Either save your twenty-five bucks and use your class notes, or buy another review text...cause this one sucks!
