I have taken this course two times and each time I took it with Ravi. Ravi is an excellent teacher and does everything he can to ensure that you understand the difficult subjects. He makes this process as enjoyable as possible by adding some humor and his own personal experiences. Ravi goes through each section at a good pace without sticking to one subject too long. If he feels as if the book is leaving something out or if there is a better way for something to be done, he does not hesitate to show you certain shortcuts that are extremely helpful. Ravi teaches you in a way that does not feel like teaching, its almost as if he tries to make it as simple as possible while still drilling in the important aspects of test taking.
