    Very informative

    Tons of information, I bought the nook version which is color this really helps when your working with the insides of the computer. The book version is black and white but does contain a nice practice CD. I also followed this up with buying A+ for dummies paperback the CD that comes with this book is a must.

    Dear Barnes & Noble technical support: Please know the "

    Dear Barnes & Noble technical support: Please know the "CompTIA A+ 220-801 and 220-802 Authorized Exam Cram" NOOK-FOR-WEB version is the old, UNCORRECTED version. This old version contains errors that have NOT been corrected. The corrected version only appears via the Windows 8 Nook app or via the NOOK-FOR-PC program on Windows 7. But the NOOK-FOR-WEB version of this book needs to be replaced with the CORRECTED VERSION!!!
