<p>Ebay and Amazon are good sites, but you could also try asking your classmates who already took the Ap’s, and are willing to show you their old books.</p>
<p>I honestly truly dont want to sound like an advertisement, but I’ve gone and found 4 different up to date popular study guides for each of the most popular AP test on my site [AP</a> Pass - AP Test Calculators, Study Guides, and Resources](<a href=“http://appass.com%5DAP”>http://appass.com)</p>
<p>They are all just links straight to amazon, but it might help simplify your search, and most of them are only around 13 bucks anyway. (just look under “calculators”)</p>
