Manhattan GMAT's 8 preparation guides were developed by Manhattan GMAT's talented staff of real teachers, all of whom have scored in the 99th percentile on the official GMAT. As the company focuses solely on the GMAT (no other tests), it continually updates the guides to reflect the GMAT's most current trends. Questions are refined and strategies enhanced, blending the academic and test-taking skills that have been essential to the success of Manhattan GMAT students around the world. The nation's largest GMAT-exclusive preparation provider, Manhattan GMAT was founded by Zeke Vanderhoek. A Yale graduate, Zeke taught as a member of Teach for America at New York City public junior-high school, earned a Masters in Philosophy & Education from Columbia University's Teachers College, and supplemented his day-job by tutoring individuals in various subjects at all educational levels. Word-of-mouth referrals soon brought in a remarkably high number of GMAT test-takers, and thus Manhattan GMAT and its prep guides were born.
