Dropping classes at UCs?

<p>I’m just curious, how do UCs handle dropped classes. I’m wondering because I think there’s a different system than my community college. At my community college, it goes like this:</p>

<p>Total weeks in a semester: about 16</p>

<p>0-1.5 weeks into the semester: Drop with no penalty/full refund
1.5-3 weeks into the semester: Drop with no penalty/no refund
3-12 weeks into the semester: Drop with ‘W’ notation (you can drop for any reason, teacher permission not required)
12-16 weeks into the semester: You may not drop anymore</p>

<p>How does the dropping system work at UCs? I’m going to UCSB, so I guess I’m looking for the quarter system dropping system (not the semester system of UC Berkeley).</p>

<p>All the information is listed at <a href="http://www.registrar.ucsb.edu/deadline.htm%5B/url%5D"&gt;http://www.registrar.ucsb.edu/deadline.htm&lt;/a&gt;&lt;/p>

<p>So basically, you can drop without a $3 fee after one week, and then between 2-3 weeks, you get charged $3 and get a 100% refund on fees? Are W's not assigned or something at UCs?</p>
