Test experts recommend that you prepare for the GRE over a period of at least three months. You have a complete spectrum of options for GRE preparation available to you, and you will be able to choose how to prepare based on how much time you have, your learning style, and financial considerations.
ETS will mail you a CD-ROM with practice tests and other study aids when you register for the GRE. The CD-ROM is free, and is a great place to start. Take one practice test under realistic, test-like conditions, as a pretest. Then you can evaluate how much test preparation you want to do. Free practice tests are also available online from the ETS website, and from www.princetonreview.com and www.kaptest.com.
Kaplan and Princeton Review are the trusted leaders in GRE preparation, although other companies such as Barron’s and Peterson’s also have produced good review books. Princeton Review and Kaplan both offer a wide range of products and services: review books, individual tutoring, and prep courses. The review books are the cheapest option for GRE preparation, in the
$20-30 range. These books also come with CD-ROMs. It will be important for you to take several practice tests under test-like conditions, if only to get used to the experience of sitting at a computer answering test questions for three to four hours. However, working through the various types of questions on paper, as you go through a review book, will also be very helpful.
If you decide to take a prep class, you can be confident that you will improve your score -- both Princeton Review and Kaplan offer money-back guarantees. Currently, Princeton Review charges $1049 for an eight-week course, and Kaplan charges $1099.
For individual GRE preparation tutoring, whether through Kaplan, Princeton Review, or an independent tutor, expect to pay $40-50 an hour. This can be a great option if you learn best in a one-on-one setting, or if you are basically an independently motivated learner who just needs to clarify a few points on the content of the GRE or on test strategy.
