When should I start prepping?

<p>I'm currently a high school senior and I would really like to go to grad school (actually I know I will go, so I will need to take this test).</p>

<p>I want to know when I should start studying? What books to use? I'm aiming for perfect. </p>

<p>Please don't say "it's too easy, enjoy life." I know. And I will enjoy life if I don't cram it all in in a 3 months period (which it seems like everyone is recommending). I got a 2150 on my SAT first try (if that makes any difference)</p>

<p>Thanks <3</p>

<p>Wait until your second or third year of undergrad before you start preparing for the GRE.</p>
