Erfun is a professional GMAT tutor based in Manhattan, with over 12 years and 12,000 hours of standardized test tutoring experience. He has been a full-time GMAT tutor for the past nine 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 is one of the few people in the world who can boast of having scored in the 99th-percentile (760+) on all four of his GMAT attempts, including a perfect Quantitative score of 51 and a Verbal score of 48 (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’s one of the most consistently well-rated GMAT tutors in the world, as evidenced by the numerous 5-star testimonials of his services.
