I nearly failed my exam due to this book. It rattles on about things that aren't in the exam, it doesn't explain things clearly, and the stuff that really matters, it hardly touches.

Also, there are many errors in the book. The practice questions included are quite often wrong, and the answers don't fit the questions.

Honestly, I've lost faith in the usually brilliant 'For Dummies' series.

Get the Sybex or Mike Myers books if you actually care about your IT Career.

I am studying CompTIA A+, I am studying with Computeach and have been using Labsims too. I can safely say that anything you want to know and MORE about the CompTIA A+ Essentials and IT Tech qualifications it's all included in this book or should i say 9 books in one. I strongly suggest anyone taking the exam should buy one of these books. Good Luck.

5.0 out of 5 stars Covers the Test and What You Need to Know 6 Feb. 2007
By John Matlock - Published on
Format: Paperback
This huge book, or as the front cover says, 9 Books in 1, covers CompTIA A+ exams 220-601, 220-602, 220-603, and 220-604. It takes over eleven hundred pages to cover everything, and then has a CD with the 'For Dummies' test engine and hundreds of sample question.

The book basically covers two areas:

First is the material you need to know and understand about computers in order to pass the test. This covers simple things like what's a motherboard to security in networked systems. It is written in the typical 'For Dummies' manner, that is, light and easy to understand, but with all the bases covered from the big picture (is the power on) to the small details.

Second is the part specialized to the test itself. This covers everything from what the test is about, to what to do on the day of the test itself to give yourself the best possible chance of passing.

All of this is combined with the usual humorous writing common to the 'For Dummies' books that help to make them a bit more interesting. And of course there are Rich Tennant's cartoons between the major sections.

3.0 out of 5 stars Good book, but test engine has tons of bugs! 24 May 2007
By Sean Seymour - Published on
Format: Paperback
I generally like the Dummies books because they are surprisingly comprehensive and very readable. This one was no different, but I wanted to warn A+ test takers that the "Test Engine" on the cd has a large amount of bugs. Like you will choose the correct answer, but it thought you chose a different one, or the question won't match the answers, etc. There are 724 questions and I would say at least 50+ bugs. So if you use the cd (which is definitely useful) just be careful and check your answer with the book if you think the engine made a mistake. I have the 2007 edition, ISBN 978-0-471-74811-3, and hopefully they will fix the bugs in a later version.

4.0 out of 5 stars Easy to digest 30 May 2007
By Samantha - Published on
Format: Paperback Verified Purchase
This book was recommended to me by my tech support guy, who is very knowledgeable. I picked up this book because I am tired of not knowing how my computer works and I want to be able to help others with their computer problems, possibly in a work setting where I could increase my paycheck and/or switch jobs by getting my A+ certification.

The main drawback of this book is that it contains more than a few proofreading errors, but despite that annoyance, the content and organization of the book are very helpful. The best thing about this book is that the chapters are short, which makes the gigantic book seem a lot more manageable, and there are short quizzes at the end of each chapter which will allow you to see if you've actually retained and understood what you just read. Though concepts are generally explained simply, if you do not already have at least an intermediate knowledge of computers, many parts of this book will probably be above your head. If you're not already fairly well-versed in computers, I would recommend reading PC Troubleshooting for Dummies and learning about the innards of your computer before venturing into this book.

2.0 out of 5 stars A+ certification all-in-one for dummies 12 May 2007
By Russ - Published on
Format: Paperback
Book is not separated into test objectives. All 1100 pages covers all tests. If you are not wanting to take "Depot" or "Remote," You still must read ALL chapters to cover information required for basic tests. The book is very well written and explains topics in detail. If the book was separated into test objectives, I would give it 5 STARS

2.0 out of 5 stars The real story 29 Oct. 2007
By Colonel Abrams - Published on
Format: Paperback
I titled this the real story because these are the things you need to know before buying this book. First, yes its 1100 pages; big because of the "improved" A+ update. The problem isn't the size, its the organization. To become A+ certified you have to pass A+ Essentials & one "elective" (IT Technician, Remote Support, or Depot Technician) One would assume that there would be one section dedicated to A+ Essentials, and others for the aforementioned "electives" but there isn't. There are no sections that start off saying "Remote Support" then teach you everything about that particular "elective" etc. Everything is mashed together. If the book was as short as the previous version then this probably wouldn't be a problem for most people. But again its 1100 pages, of technical stuff; why read about technical stuff pertaining to Remote Support when you're studying for Depot Technician. The software is pretty much a joke. It's not adaptive (then again neither is the real exam for now) so it can't really help you learn your strengths & weaknesses. You're just being asked 750+ questions with no interactivity (no test engine at all) so it doesn't help all that much. There's also the quick assessment tests that are nothing more than pdf files that you open and read. They are 2 page files that contain between 5 & 10 questions. The first page has the questions and the second page has the questions with answers. The only reason I gave this book 2 stars is because of the amount of info in it and work that went into it, but its the worst Dummies tech book I've bought; My opinion, wait for the next release or make sure you buy study material for the "electives" you're studying for.
