About study books...

<p>Does the year published matter, specifically for PR's Econ and Peterson's Calc books. I'm looking at buying the 2004 versions of each but I'm not sure if the tests have changed enough since then to make a difference.</p>

<p>Thanks in advance</p>

<p>I have a copy of the 2008 edition of PR’s AP economics, so I compared it to the preview of the 2004 edition I found on Google books. Result: the books are, for the most part, exactly the same. </p>

<p>Furthermore, I found the 2005 AP economics course description (oldest one I could find), and it is exactly the same as the current AP economics course description.</p>

<p>The 2004 edition for calculus should also be fine. My teacher gave my calc class both the 2003 released calculus exam, and the more recent (2008) audit exam, and they both covered the same material and had the same sort of questions.</p>

<p>Thank you so much for the help <3</p>
