Biology E/M- Accuracy of practice test scores from blue book and PR?

<p>I've been studying out of the PR book and took the two tests in there as well as the test from the collegeboard book with all of the tests in it. My scores were significantly better with the blue book, so i'm not exactly sure where I'm at. How accurate are the practice tests from these books to the real thing? And if you don't mind, what did you get on your practice tests compared to your actual test score?</p>

<p>Good luck to everyone testing tomorrow! :)</p>
