Part of the TotalRecall: The IT Question Book Series, this new book fills the gap existing in the complete study aid material available for candidates preparing to set the CompTIA A+ Core Hardware Exam. This book covers information associated with each exam topic in detail and includes information found in no other book. This manual is designed to provide information to help readers study for and pass CompTIA"s A+ Core Hardware certification exam. Every effort has been made to make this manual as complete and accurate as possible. Just reviewing the table of contents, you will see that through TotalRecallPress, I was given the freedom to build on what I have learned from running a Voc Tech school. For example, the chapter numbers are written in Base 2. This wasn"t done to annoy you. The goal is through reinforcement, learn binary math, since that is how much of computing works. This title (ExamWise) is a "I just want to make sure I know what I think I know before I spend a couple hundred bucks on 220-221." This book contains over 450 questions directly related to the A+ Core Hardware certification topics. If you want/need a certification/reference/killer idea book with the additional goal of taking 220-221 , try the InsideScoop to A+ Core Hardware ISBN 1-59095- or ExamInsight for A+ Core Hardware ISBN 1-59095-220-0 from TotalRecallPress. The InsideScoop to A+ Core Hardware book with BFQ CD exam has enough data to keep anyone busy studying for the next year.
