<p>Any opinions on the "best" do-it-yourself prep for the GRE? Kaplan? Princeton Review? Something else?</p>
<p>What's on those CD's that come with the prep books?</p>
<p>Thanks!</p>
<p>I used Kaplan, but mostly I found the practice tests to be the most useful. The CDs contain extra practice tests other than the ones that are provided free by collegeboard. If you did well on the SATs, not much studying is needed as they are really similar.</p>
