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.
The book contained lots of useful information, however the questions are very different from the actual MCAT. Overall good book for learning the basics of all sections. Everything is laid out in an easy to read format.
I really like this test prep book for the MCAT. It was easy to use and easy to understand. At the beginning of each section, they have pages that you can read to brush up on things that you might’ve forgotten. At the end of the practice question they have the correct answers with explanations. Overall, it’s a good book to help you study.
