Study Guide for Mankiw's Principles of Economics, 6th

I'm a professor of economics who has used Mankiw for both micro and macro for a number of years. Last fall, the publisher sent me a copy of the study guide and I admit that I am very impressed. While the readings might not be very useful if you're already reading the text...the problems are wonderful! I am a FIRM believer that students cannot fully learn economics unless they put pencil to paper and actually practice. The benefit of the material in this over the questions in the textbook is that it provides the ANSWERS. The answers are in the back of the book and are very helpful for understanding why the correct answer is correct. I hesitate to give 5 stars because I think that some of the "advanced thinking" questions do not have one correct answer. Students could provide answers in a variety of ways that are correct and the answer key does not always acknowledge this fact. Regardless, I think it's a VERY useful study tool and I plan to encourage my students to buy it as a way to achieve high grades in both macro and micro.
