The GMAT – short for the Graduate Management Admissions Test – is tough, even for the best test-takers. And, like it or not, the GMAT is required by nearly every graduate business school. A number of very good test-prep companies offer materials, classes and/or one-on-one coaching. I strongly urge you to take advantage of their offerings, and I have great news for you: As the potential client, you are in the driver’s seat.
