<p>After doing a little research throughout this forum, I have noticed that the textbook most recommended for this AP is the “Introduction to Comparative Politics” book by Kesselman. However, after looking it up on Amazon, I found two versions:</p>
<p>Published in 2003:
[Amazon.com:</a> Introduction to Comparative Politics (9780618214464): Mark
](<a href=“http://www.amazon.com/gp/product/0618214461/ref=oss_T15_product]Amazon.com:”>http://www.amazon.com/gp/product/0618214461/ref=oss_T15_product)</p>
<p>Published in 2009:
[Amazon.com:</a> Introduction to Comparative Politics (9780547216294): Mark Kesselman, Joel Krieger
](<a href=“http://www.amazon.com/Introduction-Comparative-Politics-Mark-Kesselman/dp/0547216297/ref=dp_ob_title_bk]Amazon.com:”>http://www.amazon.com/Introduction-Comparative-Politics-Mark-Kesselman/dp/0547216297/ref=dp_ob_title_bk)</p>
<p>I know that the exam was changed in 2005, so I am pretty confused in deciding between the older version and the new version.</p>
<p>Is it necessary to buy the 2009 version, or will the 2003 version suffice?</p>
