Check with the institutions you plan on applying to. Many colleges and universities will provide the average GMAT score of applicants who were admitted to the program of your choice. This will give you an idea of which scores would be acceptable.
Purchase study materials. GMAT study books, CD-ROMs and flashcards are available for purchase online and in many bookstores. You can also sign up for a study session at your local college if one is available.
Practice, practice and practice some more. Memorization may be helpful for some facts. However, understanding the applications of business and mathematical skills is a more practical means of preparing for the GMAT. In graduate school, learning how to apply skills is more beneficial than just memorizing facts for tests.
Study in sections. The GMAT includes two writing assignments, a quantitative section and a verbal section. Study one section at a time instead of bouncing between sections. Once you have one section down, move on to the next.
Complete a practice test. If you have purchased study materials, you will likely have access to a practice test. If not they are available online. Take the practice test in the same manner you would the regular test. Sit in a quiet room and take the examination without study materials. This will help to determine how well you may do on the actual test.
