Bob is the best of the best for GMAT tutoring. He is patient and very methodical in his teaching. I was shocked at how easy the GMAT exam was for me after working with Bob. I had not looked at a single GMAT problem when I started tutoring with Bob and I did not use any other study materials. With his help alone, I was able to score in the 91st percentile on my first try and I will continue to work with him to improve that score even more. Best tutor in DFW without a doubt!
