<p>So in preparation for the Bio subject tests I got PR, Barron's, Kaplan, and then got some Sparknotes tests to do. Most of the content I studied was from Barron's and PR. </p>
<p>When it comes to the practice tests I usually score 750+ for Sparknotes + PR, high 600s - low 700s for Barrons (I know the tests are usually harder), but when it came to the Kaplan test, I was unfamiliar with some of the questions and did not do too well on the practice tests. It's too late to go through the Kaplan book, but I really just wanted it for the practice tests anyway. </p>
<p>But should I be worried that I'm lacking in knowledge for some of the problems for Kaplan? I continue to do good on the practice tests from other books. Which book has the best practice tests in terms of closeness to the actual thing? I don't want to have to go through Kaplan's material if it's unlikely that it contains material that is unlikely to be tested.</p>
