Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Don't be misled by title and lack of description

I bought this book thinking that it contains all answers for the problem. This book is thin and only contains limited number of answers. It skips lots of answers for the problem. It'll be good if you want to do selected problem, but it's not good if you need answers for every questions. It's over $50, and it's not worth it. Fortunately, my professor gives class whole answers from Instructor manual.
