<p>If I sign up for summer classes now and decide I don't want to take them later, there's a $100 cancellation fee or something like that?</p>
<p>Also, if I sign up now, when are the fees due? I've looked at the website but couldn't find any information on it. If I cancel before I pay anything, will I still lose the $100?</p>
<p>One last thing, if I'm at Berkeley over the summer, is it easier to find a campus job?</p>
