<p>Swarthmore’s A.P. credit for various exams is listed here(<a href=“http://www.swarthmore.edu/Admin/registrar/page.phtml?sidebar=policies&content=apcredit)%5B/url%5D”>http://www.swarthmore.edu/Admin/registrar/page.phtml?sidebar=policies&content=apcredit)</a>, and it looks like get a little more credit for the bio exam. On the other hand, you need a 5 to get credit for either, so if you think you’re more likely to do that on Environmental Science then that might get you the better credit.</p>
<p>I think that bio is also viewed as a slightly more difficult (and therefore appealing) course, but I’m less sure about that. Any AP science is impressive, so go ahead and take what you’re interested in.</p>
