SAT Lit--huge discrepancies between Kaplan & PR?

<p>I'm taking the SAT Literature subject test for the first time on May 4th, and have been using both the Kaplan and Princeton Review prep books to study.</p>

<p>On the Kaplan tests I do well, with scores ranging from 780-800, however on the PR tests my scores range from 620-700, a huge difference!</p>

<p>Do you think the actual test is more like Kaplan's or PR's? I'm really freaking out that it will be more like PR's and so I will end up doing really badly:/</p>

<p>Any other advice/experiences would be much appreciated!</p>

<p>thank you!</p>
