I had been very stubborn for a long time trying to study for GMAT by myself. Then I realized that doing well in GMAT is really about knowing the shortcuts and having the ability to think like the test maker. After reading the reviews of various test prep companies, I decided to go with Veritas Prep. Ravi is a great instructor; he is very attentive and wants to make sure that everyone in class understands the material and key takeaways. He answered all the questions I asked via online chat during the class. Because the class is very fast paced, you will need to do some pre-course work before the class. Overall, I would highly recommend Ravi and Veritas Prep for anyone planning to take the GMAT.
