<p>I took the GRE in the fall of 2012, and I generally recommend studying with prep books. Test prep courses were never worth the cost to me, but it depends on what type of student she is. If she needs the motivation that comes from being in a classroom setting or if she works better with a tutor or something similar, then a prep course could be well worth the money. If she can self-study well or if she just needs a review of the material, then getting a good prep book should be sufficient. She should definitely get the most recent prep books because the GRE got a complete overhaul in the fall of 2011 and the most recent books will probably have the best tips and practice problems.</p>
<p>I do recommend she familiarize herself with the format of the test because the computerized set up is different than she might be familiar with. As others have said, the math level is similar to the SAT, and if she’s taken high level math courses, a review will likely be sufficient. I’m coming from a science background and I haven’t taken a writing course in years, but I found the verbal and writing sections very do-able. I know people who drill vocabulary words, but that’s never been very helpful for me. I did a handful of practice tests and questions before the exam and would look up words as I needed them, which was more than sufficient for the actual exam.</p>
<p>For what it’s worth, for my preparation, I got a the ETS official guide (which I don’t recommend because most of which can be found free online, including the two practice tests) and the Kaplan guide (I got the verbal guide as well because I was more concerned about the verbal section, but I only got through a couple sections before taking the exam). I mainly wanted something with a lot of practice tests, which Kaplan has, and I recommend taking the practice tests on the computer so that you can be familiar with the format and staring a screen for a couple of hours. I found the ETS practice tests were very, very similar to what the actual test was like, so if nothing else, I recommend doing those.</p>
<p>I would also like to suggest that she look at schools she might be interested in attending. It sounds like she hasn’t decided on a particular field or program yet, and it would be worthwhile to see what some of the requirements are. Not all schools require the GRE, and some require the general test and recommend or require a subject test.</p>
<p>I wish her the best of luck! As someone else mentioned, the GRE is often just a cutoff mark that she needs to pass over. Depending on the field, one part of the test might be weighed more heavily than another part of the test. A good GRE score can help, but a bad one won’t keep her out as long as it is over whatever arbitrary cutoff the school may have.</p>
