To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
This book was terrible. First of all, there were so many spelling and gramatical errors. It was as if the author did not speak English. Next, the formatting is atrocious. There were missing answers and pictures. The pictures were black and white and somethimes they were inserted into the pervious question. Not to mention, on the cover, it lists the book as a Missouri test manual but if you open the book, on the first page it says Arkansas manual. However, that is not the worst part. I counted over 30 repeated questions in this book. If I could rate this book 0 stars I would. DO NOT BUY THIS BOOK. IT IS TERRIBLE.
