<p>I want to self-study for the AP Psychology test, since Psych couldn't fit into my schedule this year. My brother took AP Psych in high school, and he has a copy of Barron's he said I could use. However, it's a 2nd edition, and the latest edition of Barron's for AP Psych out is the 3rd. Would the 2nd edition be just as good, or should I be safe and buy the 3rd?</p>
<p>I got the 3rd edition, some of the content is different from Myser’s Textbook(I have the Canadian version)</p>
<p>There is a ‘2008’ version too.</p>
