Getting a high score in the GMAT is not easy. You need to work hard and, what is even more important, know HOW to work in order not to waste your time. It is even harder if you have to combine study with a full-time job, as was my case. However, Kevin in his lessons teaches you the right methodology to prepare properly and efficiently for the test: he offers you a wide variety of material and explains how to focus in really important things (the things that you will actually be asked for ). In the classes you will learn useful clues that will be essential on the test day, and individual lessons are essential to focus in the areas where you feel less confident. I got a 740 in the exam just six weeks after the course began! I highly recommend this course to everybody who wants to perform really well on the GMAT, specially to those people who, as me, do not have much time to prepare it.
