Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Poorly Edited

There are review questions at the end of each chapter. I have progressed through Chapter 11 to date. Every single review section contains questions that cannot be answered by information in the text. Replies from the publisher revealed that needed information was deleted in the editing process. Their suggestion was to buy the next edition. (Customer service at its best, eh?) My suggestion is to skip this book altogether and find a better edited Networking Fundamentals guide.
