What better way to ace the AP exam than to learn from someone who aced it himself? Professor John Zhu brings together education and teaching experience to Educator's AP Calculus AB course.  John explains complicated calculus ideas in easy, understandable terms so that any student can succeed on the exam. In addition, all the topics on the test are covered with many extra examples, as well as a full length practice test at the end of the course. Topics include an Overview of Functions, Derivatives, Integrals, Area between Curves, Revolving Solids, and Differential Equations. Professor Zhu received his B.S. in Electrical Engineering from Michigan State, his MBA from Webster University, and has been teaching AP Calculus for over eight years.
