Princeton Review Physics - Accurate?

<p>How accurate are the Princeton Review's SAT II Physics Tests? I just took a practice test out of it and It's scaling my score to about 750. What can I expect on the real SAT II? </p>

<p>Or maybe a better question would be, is the Physics SAT II harder or easier than the Princeton Review's or is it pretty accurate?</p>

<p>Thanks.</p>
