Take a practice test. The Princeton Review recommends that potential test takers do this first. It will help you to assess your strengths and to familiarize yourself with the test. Free practice tests are available on the Internet.
Familiarize yourself with the format of the test. Taking a practice exam should have been your first introduction. The GRE has three sections: an analytical writing section, a quantitative section and a verbal section. Determine how much time you will have for each section, how many questions are on each section and what types of questions are included in each section. Doing this will save you time when reading the instructions on the real exam.
Study. You have taken a practice test and familiarized yourself with the format of the exam. You should have a good idea of what your strengths and weaknesses are. Schedule study time for each day. Spend more time reviewing the material that you are least familiar with. Educational Testing Service, the company that develops and administers the GRE, offers free study guides to everyone who registers for the exam. There are also study guides available for purchase.
Take more practice tests. Do this at regular intervals. Remember, practice makes perfect. Taking additional practice tests also allows you to track your progress. If you have made progress in one area and not in another, adjust your study schedule accordingly.
Consider taking a GRE preparation course or hiring a private tutor. The Princeton Review and Kaplan offer both of these services. Tutors and course directors are familiar with the GRE. They possess useful knowledge that can be passed onto you. The individual attention you receive may mean the difference between an average and an exceptional score.
