Next Steps

The GMAT test consists of analytical writing, verbal reasoning, quantitative reasoning, and integrated reasoning. All of these test aspects are combined into a test that takes more than three hours. Additionally, there is a limit imposed on the number of times that one can take the test. Currently, according to The Economist, one has the option to take the test up to eight times. Self Study is a viable option, and there are many resources available to students who choose this route due to time constraints or financial reasons. A GMAT fundamentals course, self-paced course, or online prep course can help. Practice exams and video lessons are an excellent first step, allowing one to access areas of strength and weakness. Practice on the analytical writing assessment may be more difficult. Classic study guides from sources like the “GMAT Grail” series by Aristotle Prep are another alternative based on the actual GMAT exam.

Additionally, free resources are available throughout the internet and at the graduate management admission council. GMAT Club points out that while self-study is a viable option, distance GMAT prep courses offer distinct advantages. They have many GMAT prep courses listed. These GMAT classes are led by experts who have experience and excellent results on the GMAT. They save time by directing students on what to study for full-length practice exams and practice questions with their diagnostic tests. There is a confidence that the best gmat course covers every area that is needed, and doesn’t miss anything. Also, for those who may need it, there is a schedule to provide the drive to get everything done. Many distant GMAT prep courses offer guarantees on score improvement through their GMAT practice exams. So, a wise option might be to do a bit of both. Most GMAT prep courses cost quite a bit, but assuming that one has the time and can afford the cost of a prep course to build GMAT skills, what harm can be done when there is a refund available?
