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.
So far, everything is in line (pagination and footnotes) with the hard copy of the book my professor has assigned. Much better than the publisher’s ebook which is only available via browser access while actively connected to internet; this is a typical kindle book with offline and app access. Great to be able to search, notate, search highlights by color, etc.
