<p>Are 2008 AP prep books too old to be used? I'm planning on self studying AP Psych this year and my friend offered a 2008 Barrons AP Psych book and I was wondering if that's too old. Thanks!</p>
<p>Most of the time, they’re the same thing.</p>
<p>No, you should be OK.</p>
<p>AP books are just like SAT books; the content in them don’t change much over the years, unless maybe it’s a book about history.</p>
<p>Even then, most AP tests stop at the year 2000.</p>
