Read an overview of the test format. On the official GMAT website, the format is explained in terms of section content, timing rules, scoring procedures and frequently asked questions. Providing yourself with a better understanding of what lies ahead will help you study more efficiently and practically.
Download the official GMAT preparation software from the official website. Titled GMATPrep, the software is free and helps simulate test-taking conditions. While GMAT preparation books may help you prepare in terms of content, the GMATPrep software will also enhance your familiarity with the computer-based version of the test. If you perform better in a structured environment rather than relying upon your own motivation, consider enrolling in a GMAT preparation course.
Evaluate yourself after each study session. Specifically target your weakest areas. While it is not a good idea to completely ignore sections in which you naturally perform well, focus more attention to improving your weakest elements of the test. If you can successfully turn your weak areas into strong points, then you should put yourself into a position to perform very well come test day.
Take as many practice tests as possible. Previously administered tests are sold as practice study guides. Become familiar with the timing of a test. By the time you take the actual GMAT, you should have developed an internal sense of time. The ability to sense when you are spending too long on a section or whether you have time to come back to a question later on is critical in your performance. If you get lost in a difficult question, you may waste precious time that could be used to answer five or six other questions correctly.
Track your progress. Whether tracking study habits or mock test scores, visually recognizing your own improvement will help bolster your confidence leading up to test day. Monitor your progress in various study settings. For example, do you perform best after studying with peers, an individual tutor or by yourself? Experiment with each option and then determine which best fits your study habits. It may be a combination of two or three different settings that works best for you.
