I never took the AP microeconomics course offered at my school. I just used this book and the PR book. Overall, this book is great in that it teaches all the information needed to ace the test. However, the questions in the practice test are not reflective of those on the real test. Also, sometimes, this book delves too deeply into the subject. It provides far more information than is necessary to get a 5 on the test. It is also more boring than the Princeton Review book. Information is presented in paragraph forms rather than in bulleted form, making it more unorganized. However, knowing this book back to front will easily get the job of getting a 5 on the AP test accomplished.
