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.
From the seller, this book was not in good quality condition. I would've called it "acceptable" at best and the binding fell off after a couple of months.
But regarding the text itself, this is probably one of the worst textbooks out there. This dense and garrulous 700 page trash finds ways to turn every simple concept into multiple pages of unrelenting wordiness. The author seems to have a poor talent in articulating anything at all. Annotated visuals would've actually taught the reader something instead of wasting a ton of his time by forcing him to endure countless pages of text. Find a different source to learn from even if it is a required material for your class.

I had to read this textbook for class, but I didn't learn anything from it. There are long paragraphs which overcomplicate things. The references to the diagrams are poor. There is no indication of what something is in the diagrams; there's just numbers and boxes. Chapter 2 is about 60 pages but it could've easily been broken down.
