Edition of prep book

<p>Hi,</p>

<p>I am looking to buy a prep book for ap gov and macroecon.
I have never gotten an ap prep book and was wondering if needed to buy the most recent book. I know the 2015 books just came out but is it fine if I get the 2014 or 13 books?</p>

<p>Thanks</p>

<p>I believe they should be fine as well. The subject matter doesn’t change on a yearly basis. The AP exam also hasn’t changed. Unless there will be major changes such as those to AP U.S. History or so, you can buy an older version.</p>

<p>For Gov and Econ, the tests have not been redesigned. The content of the tests is the same year after year, and so is the information in the review books. The new editions are often exactly the same as the old ones.</p>
