Manhattan Review's GMAT prep classes give our students the benefits of the latest innovations in teaching and learning theory in addition to our many years of experience with prep tutoring. Some of our competitors are reluctant to undertake the effort and expense of keeping their course materials up to date. At Manhattan Review, we understand that giving our clients the best possible service means constantly reviewing and revising our teaching methods and materials to reflect new ideas. We also take full advantage of testing statistics compiled by our research team, because this helps us better understand the needs of our students. When you sign up for a Manhattan Review GMAT prep course, what you get is a result of the tireless labor of tutors, researchers, and educational theorists.
