Query: Supplement Only

There are many practice exams in this book, scattered among other filler material, but only a few will really prepare you for the real thing. This would be a good supplement to better test preps such as the GRE/MCAT or other Civil Service Exam math prep books. Some of the materials are completely irrelevant to the FBI and appear to just be a compilation of other occupational exams that were photocopied and bound in some guys basement in the mid 80's. I was successful in the real exam but would only use portions of this book as a part of one's study routine.
