Which prep company is best?

<p>As you know, the collegeboard only gives us a measilly 1 practice test for the Subject Tests.</p>

<p>For SATII Chemistry, which company has the most accurate practice tests?</p>

<p>Here are my scores from each, and which one seems most realistic?</p>

<p>Princeton Review (790)
Kaplan (740)
Barrons (haven’t taken)</p>

<p>I’d say the Barron’s one seems more realistic.</p>
