Ravi Sreerama is a really nice and helpful instructor. He truly cares about all his students. He makes bored course materials into fun course contents, and he will train your time management skill by teaching you the time control method on answering different types of GMAT questions. Also, he will make you think like the test makers so you won't be trapped by the tricky questions. Logic is the key to success in GMAT, I definitely recommend Ravi to everyone who is looking for a good GMAT prep course and wish to get a high grade on the GMAT exam.
