AP Chemistry Premium Prep is a book used to prepare students taking AP Chemistry for the AP test in May. It very thoroughly covers all topics required by the College Board from the textbook, by unit. In addition, there are brief multiple-choice practice questions after each chapter to help a student review. There are plenty of tips for how to approach the long free response question section. The book contains multiple full practice tests as well as more online tests that you can print out and use.
The practice tests in this book are slightly harder than the actual test, which helps you prepare well. There are seven tests, so you can get plenty of practice. This includes high-quality, challenging multiple-choice questions. There are also plenty of free-response type questions, which is good practice for students who want to get used to the long length of the test. Because of all this, I give this book a five out of five.
