The GMAT exam is one of the metrics that is often required to get into the business school of one’s choice. The Economist offers insight into the importance of this standardized test. The GMAT is a window into one’s ability to learn a set of content over a short time. It measures test-taking acumen and whether or not one has a penchant for quick decision-making. U.S. News quotes Lindsay Badeaux, a senior assistant director of admissions at the University of Chicago’s Booth School of Business, saying that the GMAT is “a strong indicator” about one’s readiness for business school. With so much on the line, students are looking for the best online GMAT prep classes.


The GMAT test takes about three-and-a-half hours, and it has four parts. One part is a writing assessment that measures critical thinking and communication skills. Another portion involves integrated reasoning. In this section, one analyzes data and interprets information that is illustrated in differing outputs. A third section is quantitative reasoning. This portion of the test asks the question of whether an individual has solid math skills. A final part consists of verbal reasoning. This section determines if the test taker is proficient in reading comprehension, editing, and following written arguments. 

Self-study for the GMAT requires a lot of discipline. The consensus is that a preparation class or private tutor are more reliable routes, and help one better stay on track for the 80 to 90 hours of study that many put into the test. The following list of the Best online GMAT Prep Classes is a great place to begin.

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. Practice exams are an excellent first step, allowing one to access areas of strength and weakness. Classic study guides from sources like the “GMAT Grail” series by Aristotle Prep are another alternative.

Additionally, free resources are available throughout the internet. GMAT Club points out that while self-study is a viable option, online GMAT prep courses offer distinct advantages. They are led by experts who have experience and excellent results on the GMAT. They save time by directing students on what to study. There is a confidence that one 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 online GMAT prep courses offer guarantees on score improvement. So, a wise option might be to do a bit of both. Assuming that one has the time and can afford the price of a prep course, what harm can be done when there is a refund available?
