Scored a 775 on the GMAT
100+ GMAT clients
Welcome! I'm an expert in all areas of the GMAT itself (most recent score: 775: 90Q, 90V, 86DI), but more importantly, I'm an expert in how students can most effectively prepare for this test. As I say often, the sections of the GMAT are correctly named—this is a test of your *reasoning* skills, not just math and verbal skills! I have helped thousands of students reach their GMAT goals through classes, tutoring, and coaching. I also managed Manhattan Prep's Post-Exam Assessment program for many years, during which I helped students who felt stuck for any reason reassess their preparation and make the right changes to lead to GMAT success. In particular, I have extensive experience working with students dealing with test anxiety and/or GMAT burnout.
