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 analyses reviews to verify trustworthiness.
The book was very funny and all, but I wasn’t too thrilled by the weird marks on random pages. And it was clearly visible that the book was just a photocopy of the original book. Didn’t expect such a thing from Amazon. Very disappointed.
