From an A+ Instructor, By
This review is from: CompTIA A+ 220-801 and 220-802 Authorized Exam Cram (6th Edition) (Paperback)
As a long-time A+ Instructor (18+ years), the CompTIA A+ 220-801 and 220-802 Authorized Exam Cram series is one that I have recommended to every student I have ever had, regardless of the book(s) we used for our classes. For all my students, I can honestly say that this series is worth every penny. When I personally prepared for the A+ exams myself, I used this series exclusively and missed one question total (on both tests). I firmly believe in this series and what it can do for the student looking to pass the A+ exams.This book is not just a fine example of a new edition with all the new content added in, it is a significant improvement. The book is written in a much clearer format than any of the previous editions; it is a readable document, not a technical manual. The questions and answer format follows everything I have learned to expect from the series. The book provides, not just questions and answers, but the logic behind the right and wrong answers...

This book for Comp/TIA A+ 220-801/220-802 exams is a very good study book, By Boomer (MidAtlantic) - See all my reviews
This review is from: CompTIA A+ 220-801 and 220-802 Authorized Exam Cram (6th Edition) (Paperback)
This new book for the Comp/TIA A+ 220-801/220-802 exams is a very good A+ study book, and one of the firsts for the new exams. I like how the chapters are broken into segments with a few questions right after a topic is covered, instead of a whole bunch of questions at the end of the chapter. This is especially helpful with the longer chapters. The cram sheet at the front of the book is still one of the things that really make the exam cram books stand out, and I found it to be very useful. The paper exams are in the back of the book are thorough, and I like how the answer key provides the chapter that the question comes from to help you review wrong answers (though I would have liked for the book to provide page numbers instead of just chapters). The CD in the back of the book really has some very nice study tools including a PDF file of all of the Exam Alerts from the book. Also the authors of the book assume that you have a fair knowledge of the subject matter, so if you are...

A Great A+ Preparation Tool,
Amazon Verified Purchase(What's this?)
This review is from: CompTIA A+ 220-801 and 220-802 Authorized Exam Cram (6th Edition) (Paperback)
I've been teaching A+ and other topics for 14 years and I've taken over 25 certification exams, so I know what good materials look like. The Exam Cram A+ for 801/802 is an outstanding resource, and if you have some computer background it may be the only resource you'll need to do very well on the exams.I used this book as my primary resource (I passed the exams very comfortably) and found it to be the right amount of detail. Some books are way too detailed and you get lost in the forest of information. Others don't cover crucial topics. I think Mr. Prowse has found the right balance. The sample test questions throughout the book and the two sample exams at the end are a great assessment tool and are similar in scope to the real exam questions. There is a very handy "cheat sheet" review card in the front of the book which is a great review tool after you have done your studying. I will be recommending this resource wholeheartedly to my students by all... Read more |
