Query: If you buy this, you probably deserve to be slapped.

Let me first say I own this book, and have read it cover to cover. It is garbage. A few "key concepts" in the Sec+ exam are barely even covered. In its defense, it is not as dry as many other technical books, but I'd take a dry book with some substance over a interesting book that teaches me nothing. Don't take my word for it though... look at the preceding reviews!- "Incorrect "facts" and poor organization"- "Lightweight textbook"(Is that really a plus? So is an empty notebook!)- "...shouldn't be relied on as the only resource"- "...only reason I bought this book is because it was for a class, otherwise I would have chosen a different book ...)- "Not worth the money"and the list goes on... Find a different book, not too many out there that won't beat this one!
