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.
Absolutely loved the book, just what I wanted! To save money I bought it used. It was said to be in excellent condition, however when I got it it was sooooooo dirty and a page was ripped! I had to wipe it clean with soap and water, i tried just water at first and it wasn’t coming off :( Super unimpressed with the buyer I used. Not sure how they grade the quality of the used books but it should be changed.
