    Great book, passed the exams

    Just passed the exams, very happy with this book. Buy it, read it carefully, do the practice exams, and go take the real test.

    Best A+ book on the market

    This book is just what a PC tech needs to pass the CompTIA A+ exams.
    But a word to the wise: if you are a newbie, get some experience on computers, and look into full blown A+ study guides first. Then use this book to ace the exams.
    Either way, I recommend buying this book...

    Best option for A+ preperation

    This book is amazing! It comes with a cram sheet, practice test questions in the back of the book, and even more questions on the CD. I tried a book by an author known for A+ and used in most A+ courses to no avail. This book prepares you more accurately and efficiently than any other.
