Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Okay, but not enough

This is a REVIEW book; it does not cover all the topics in enough depth to educate someone who is not familiar with surveying. I agree with most of the other reviewers that state it will not adequately prepare you for the exam. I was most disappointed with the overall quality of the book. I found numerous minor errors and a few things that are just plain wrong. Likewise the companion "Practice Exam" is a joke. The questions are too easy and too many are focused on definitions and regulations, not calculations and problem solving. That said there isn't anything else currently on the market for a similar price. So if you want to save the money of a review course and try studying on your own, go for it.
