Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Waste of a text

I am not an instructor in the course, like some of the other reviewers. I am actually a student working at an undergraduate level, as a Computer Science major. The poor explanations with the sectional exercises prompted me to write the review.In my honest opinion, the book is poor. It seems like it rushed for publication. Not only are the explanations poor, but the solutions for the in-book exercises are as well. I mention this, since all of my homework is lifted from this text. The book lists back-of-the-book solutions. Sometimes it will list solutions for the wrong problems. Other times it will have incorrect solutions (especially with grammar productions.)My advice is to avoid the text. If it is required reading for the course, then look for a used copy at best to purchase.
