<p>My friend and I are planning on visiting UCSC in a couple of weeks. We're totally juiced to finally be able to visit. We're not taking the usual guided tour, we've decided to just take a map and go exploring. On our agenda is crashing a class that falls into our intended major to try to get a general feel. My concern is crash etiquette. Is there a certain way to crash a class, or is it a totally taboo practice that will result in being blacklisted?</p>
<p>Oh, and are there diamonds in the rough we should visit?</p>
