943251_630419616985340_563237844_nErfun is a professional GMAT tutor based in Manhattan, with over 10 years and 10,000 hours of standardized test tutoring experience. He has been a full-time GMAT tutor for seven years, but his experiences since graduating from Yale have all, one way or another, revolved around standardized tests.

Before focusing his efforts on GMAT tutoring, he worked in New York full-time as GMAT Content Developer and Instructor for a major test-prep company, where he wrote, edited, and explained hundreds of practice GMAT questions. His immersion in the process of question-construction gave him first-hand insight into the tricks that the test-makers develop and the crafty ways they manipulate seemingly simple concepts into complex puzzles. Additionally, Erfun is sole author of McGraw Hill’s Preparation for the GRE, 2017 Edition, a 500-page, comprehensive guide available on Amazon and at all major book stores.

As a bona fide GMAT geek, Erfun has taken the GMAT three times and has scored above the 99th-percentile (760+) each time, including a perfect Quantitative score of 51 and a Verbal score of 47 (99.5th percentile). He now uses his substantial expertise in the GMAT to help students see past superficial tricks and shortcuts and understand the logic of the exam. He has helped students gain admission to some of the nation’s top business schools, including HBS, Columbia, Stern, Wharton, Stanford, and Sloan. And he can do the same for you.
