Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Don't judge a book by it's size!

I think Amazon should filter on-line reviews. The reader from San Diego, Ca, January 26 is either the author or has some financial interest in the book. Although very large in size, 750+ pages, it was poorly written. The exam questions were ambiguous and sometimes incorrect altogether. In addition, the testing software contains bugs which caused the application to crash periodically. I have not taken the exam yet, so I don't know if some of the book's material will be helpful. I am very disappointed with this purchase. The only saving grace is that I didn't pay full price. Thanks Amazon.
