I thought the book was good - while I was reading it! When I went to use the Measure Up testing software that came with it the test only offered 97 possible questions. This seemed to be a weak attempt at randomization and none of the graphics referenced in the test questions displayed! After two weeks of emailing back and forth with the software publisher tech support I was given an update to the testing software that offered 668 possible questions which only used one graphic. My biggest complaint at that point was that I repeatedly found discrepancies between the information contained in the testing software and the book! Everything from connection speeds to distances was different between the two. Some of the testing software questions were simply terrible! Obviously this leads the student to question EVERYTHING they thought they had "learned" from the book! I also found elementary typographical errors in both the book and the testing software (e.g. throughout where it should be throughput, etc.). A local testing facility said they use the Measure Up testing software, but they dont suggest a student schedule the test until they start scoring in the %90+ range.

I know everybody says use at least two pieces of study material so I started reading the Sybex Network+ book the other day. The claim that this is the "#1 Best-selling Network+ Book" only means MANY more people than me have had this incredibly frustrating experience. Save your money and buy something thats actually been developed in conjunction with the companion testing software and reviewed by a knowledgable and competent editor.

"Looking inside" above shows you the old version of this book, not the N10-003 version. You might not notice that this book has been updated though. It tells you that there are 72 questions on the test and that you have to score a 664 (?) to pass. In reality (I just took the test yesterday (and passed)), there are 85 questions and you only need a 554 to pass.

Some of the information supplied is contradictory, incorrect or not updated: the book only talks about Bluetooth v.1 at 720kps when v.2 is out and offers 2.45mbps. Other network+ books have this newer info.

The most reliable and realistic part of this book is the MeasureUp CD. Don't expect to be able to find the answers to some of these test questions in the Exam Cram book though; they're not there.

Bottom-line: You can probably pass the test with just this book, but you will run into questions mentioning things that are totally absent from the book. Spend your hard-earned dollars elsewhere.
