For more than 15 years, we have taught chemistry extensively in both the high school and private settings. One thing we have noticed throughout our years of teaching is that there is a lack of effective learning material for students of any level studying for the AP Chemistry test. To remedy this, we have produced this book. It contains all the material you need to know to get a great score. Dr. Jang believes that anyone can get an excellent AP score in chemistry in a short period of time, provided that he or she focuses on the content required for the test and the skills to tackle the questions quickly and efficiently. Here are some ways this book can help you on the AP Chemistry test and beyond: Precise But Detailed Content Knowledge In this book, we divide all of the content knowledge needed for AP Chemistry test into sixteen chapters organized with the following features: -All the facts that you need to be familiar with are directly listed. In general, high school chemistry consists of 50% understanding concepts and 50% memorizing or familiarizing facts. Of course, when you try to memorize things, being able to reason with the concepts and to understand what you're reading will help you remember them better. -More content than most AP chemistry books on the market. This book covers all the material needed to prepare for the AP Chemistry test. This book is a great study guide for your honors and AP chemistry classes. 1500+ Practice Problems and Ten Mock Tests In addition to a thorough overview of materials, this book provides over 2000 practice problems to reinforce your understanding of the material and pinpoint your weak areas that need improvement. This book contains ten mock tests at the end, more than any other AP chemistry book on the market. The ten mock tests closely mimic the actual exam and provide even more practices. By taking these mock exams with a timer under standard test conditions, students will bolster the skill set required for the real test.
