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.
I should have read the reviews before I bought this, I didn't realize this is a duplicate book, with a different title. I had already gotten the Big Nate In a Class By Himself book, which is the same as this one. I am really disappointed, as I was trying to buy my nephew each book in the series, and I purchased this one unnecessarily. Now, I just have a book that I don't need.
