Let me preface this by saying that I purchased this book solely for the logical reasoning portion of the test. I was studying for the FBI Phase I Exam (which contains a logical reasoning section). The study guide and sample tests in the Barron's book were much more varied and complex than the logical reasoning section of the FBI test, so it was nice to be over-prepared. I passed the exam, so the book worked great for my needs. I haven't looked at any of the other sections, so I can't comment on them.
