When studying for the GMAT, the individual should plan on devoting at least an hour a day to review for at least three months before the test date. The actual test takes about four hours to write, with optional breaks after the first and second sections.
Training for the GMAT is not difficult and can easily be done alone. Self-training requires a great deal of discipline; however, it saves expensive fees associated with other forms of training. If you choose to go this route, you can download free material from MBA.com or purchase guides from outside sources.
Many universities offer seminars and courses designed to prepare students for taking the GMAT. These courses are generally much cheaper than similar courses offered through private institutions; however, class sizes are much larger and there is less time spent on developing the skills of an individual student. A university course is a good idea for an individual who just needs a little extra motivation to study for the GMAT.
Private courses are much more expensive than the prior methods. Forty-two hours of instruction from Veritas Prep will set an individual back $1,400. This time also includes one-on-one training with the student, which can be the difference between a successful and an unsuccessful GMAT score for some students. Private courses are also offered online and are substantially cheaper than their "brick and mortar" counterparts.
Individuals should choose the method of training best suited for them. There are no data to suggest that any method of training is superior to the others, though any program that emphasizes one-on-one training will likely be superior to a program that does not.
You should always research a private GMAT instruction company before taking courses to ensure you will be receiving quality training.
