Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Im super upset! I wanted a digital version. Did not see Italian version. I obviously need it in English the preview was in English and looked just like the book pages. This does not. I still need the English version and cannot return or exchange. And only gave me two options to view and I dont own either of those pieces anymore.
