Prep book editions

<p>Is getting a former year, such as 2006-2007 bad when taking the 2010 exam? I'm thinking of getting the 2006-'07 version of Princeton AP Calculus since it's less than $1 on Amazon. Have tests significantly changed in the last 5 years?</p>

<p>Test format for AP Calculus hasn’t changed in the past 5 years.</p>
