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.
Excellent , but only half way through. May rate higher by the time I finish. Was looking for stories to read to children at our local library, not sure all are appropriate. I may need to use vocabulary age appropriate and check content.
