Improving a GRE Score
If you're still not happy with your GRE score, or if you want to prepare as best you can beforehand, there are a plethora of resources available. Upon signing up for the exam, the ETS will send you a booklet with a practice exam and information on test taking strategies. There are also a number of books you can purchase online or at your local bookstore that examine the three sections of the exam in-depth. The Princeton Review's Cracking the GRE and Barron's GRE by Sharon Weiner Green are two popular books. They cover strategy, helpful hints, and lists of recommended vocabulary, as well as practice exams. There are many websites offering GRE prep materials, some of which are free. Check out Number2 (www.number2.com) and a free practice test on the Princeton Review website (http://www.princetonreview.com/grad/free-gre-practice-test.aspx). GRE preparation classes are often offered, especially near college campuses. These classes can be expensive but may be a good option depending on the student. By choosing one or several of these preparation options, it may be possible to raise your score.
Now that you know what GRE scores are needed for grad school and you are now fretting over your score, it is important to remember that GRE scores are often just a part of the overall application. Graduate school programs will also take into account your undergraduate grades, experience, letters of recommendation, and other required material in addition to your GRE scores. Just like high GRE scores will not guarantee you an acceptance letter, average GRE scores won't necessarily lead to a rejection letter.
