Gruber's vs Princeton Review?

<p>Hellooo</p>

<p>This summer I’ll be attacking the SAT, and right now I have the big blue book and the Gruber’s Guide. But I’ve heard good things about Princeton Review… can anyone give me some general reviews? And any tips on memorizing vocab?</p>

<p>Princeton Review is excellent. You should pick it up.</p>

<p>Should I start with Gruber’s though? Or would that be a waste of time, and I should just start with Princeton?</p>
