<p>Yes, it’s odd.
My book looks exactly like this:
[Amazon.com:</a> Biology with MasteringBiology (8th Edition) (9780321543257): Neil A. Campbell, Jane B. Reece: Books](<a href=“http://www.amazon.com/Biology-MasteringBiology-8th-Neil-Campbell/dp/0321543254/ref=dp_ob_title_bk]Amazon.com:”>http://www.amazon.com/Biology-MasteringBiology-8th-Neil-Campbell/dp/0321543254/ref=dp_ob_title_bk)
Except above the BIOLOGY title, it says “AP* Edition.”</p>
<p>Any significant differences?
Or is it a marketing ploy?</p>
