Ok...real quick and simple, this book shows definite promise, as far as easy reading and comprehending. Although, there are MANY, let me repeat that, MANY mistakes in the practice test in the back, as well as a few other errors, but the practice test is a test in itself, while you are correcting the authors! So, if you want a good reading book, and feel like correcting mistakes, and not getting paid for it, this book is for you. If you want a book that WON'T confuse you, DO NOT BUY THIS BOOK, ESPECIALLY IF YOU HAVE NO BACKGROUND IN COMPUTERS!!! STAY AWAY!!!
