Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
This book was in good condition - probably because no one wants to read it. There is no flow from page to page...just random sentences tossed in piecemeal. I don't understand why a college would use this in their course...oh wait...yes I do...the professor authored it. I only gave two stars because the book was intact. I Almost forgot to mention - it has spelling errors. That is annoying in a college text book!
