Do Kaplan's practice test differ for every yearly edition?

<p>Wondering if every each year's edition are recycled test questions or updated to new questions? I'm assuming its new questions but just want to double check.</p>

<p>Does this also hold true with Princeton Reviews practice book as well?</p>

<p>I am looking to get as many practice questions as I can. I understand these books are not favorable by many but since I'm finished with BB I want more practice.</p>

<p>Same tests, different cover.</p>

<p>Why would somebody who is 43 years old need more practice tests?</p>
