My intuitive, common-sense approach to the GMAT has helped numerous students get top scores since 2011. I emphasize comprehension rather than memorization: Instead of just giving you rules to remember, I help you figure out why they work. There's no magic formula that makes the GMAT easy, but with my techniques, it won't feel too hard. A good GMAT tutor should meet students where they are, and I always strive to do this. If you know a concept but struggle to apply it to certain tricky problems, I can help you with that. Alternatively, if you need something explained from the ground up, I can help with that too. I am flexible enough to work within your mental framework, rather than imposing something completely unfamiliar. My goal is to find explanations and methods that work for you, even if they aren’t entirely standard. I'll make sure to warn you if you're heading in a wrong direction, but for the most part I view GMAT tutoring as an opportunity to help you leverage skills that you already have. I've found this to be a very rewarding process, and I think you will too!
