<p>I do not know about those sites or about zoology in particular. My S took one CAA class (Engineering) but 4 CTY classes, and felt that that CTY classes were better. This is a bad sample as the CAA site was ASU (which is no more a CAA site) and he did not care for engineering then, but overall he felt CTY was more challenging.</p>
<p>There are few west coast options for CTY/CAA (Hawaii is a site if she is interested in those subjects). If you are willing to send your D to PA, you may want to consider the DUKE TIP program. Their cut off scores are little lower than CTY, so you may find those classes as an option. </p>
<p>The problem that I had with many of the east coast CTY sites are that most of them do not have direct flight connections from the west coast (Baltimore is an exception). So please consider logistics before you make a decision. Airfares can get very expensive to smaller towns.</p>
