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.
Fabulous book. The graphics are just perfect. The paper quality is also very good. A must read book for everyone. Elizabette did a very great job by writing this book and also thanks to Amazon for delivering the book in a very good condition.
