Title: Decent
Review: After a couple of weeks of using this textbook, I am mostly happy with it. It does a good job of explaining the material, however, it is not very concise and takes a long discussion to make a point. It is longer than necessary and contains unnecessary features. Other than that, for the money it is a good deal, and thus the four stars.
