Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Amateurish

This book is full of errors and sample questions that are based on errors. Poor editing, really inexcusable. There is no subject matter information other than what is located in the answers. The practice exams at the end of each section does not correlate at all to the information presented in the preceding sample questions for each section.Overall an amateurish effort, very disappointing. Purchase any other study guide other than this one.
