<p>I’m taking two APs next year. AP Psychology and AP Comparative Government. And i’m just wondering if i should order them now or wait for the later edition. Is there really such a significant difference between AP tests that I HAVE to other the later editions or can i just order the 2011 editions for both(actually i couldn’t find an edition past 2009 for AP comparative government Ethel Wood).</p>
<p>There is probably not going to be a significant difference between the older and later editions. The only difference is that the intro will tell you that the way the AP exam is scored has been changed from 1/4 a point off for wrong questions, to no penalty. You can just get the 2011 editions.</p>
