Summary

Summary

Upgrading and Repairing PCs, A+ Certification Study Guide is a hands-on learning book. Scott takes the readers through the test objectives one by one. The most frequently missed questions are pointed out and explained with greater detail than easier questions need. Plain English! Spend your time learning--not deciphering bad writing! Just the essentials--Scott covers the essentials that you'll need to pass the test and point you where to go for more information. Frequent study reminders throughout help you focus and remember the core concepts for the exam - and not the not-so-necessary details. Also included are exams that will cover the topics that you'll be tested on AND we'll ask them in the manner they'll be asked on the test.
