Level of difficulty

<p>Websites for some of the classes I took this year (sophmore):</p>

<p>ACM 95 abc
<a href=“http://www.acm.caltech.edu/~niles/acm95a.html[/url]”>http://www.acm.caltech.edu/~niles/acm95a.html&lt;/a&gt;
<a href=“http://www.acm.caltech.edu/~niles/acm95b.html[/url]”>http://www.acm.caltech.edu/~niles/acm95b.html&lt;/a&gt;
<a href=“http://meiron.cs.caltech.edu/Teaching/acm100/[/url]”>http://meiron.cs.caltech.edu/Teaching/acm100/&lt;/a&gt;&lt;/p&gt;

<p>Ph 12ab:
<a href=“http://www.pma.caltech.edu/Courses/ph12/index12a2006.html[/url]”>http://www.pma.caltech.edu/Courses/ph12/index12a2006.html&lt;/a&gt;
<a href=“http://www.pma.caltech.edu/Courses/ph12/index12b2007.html[/url]”>http://www.pma.caltech.edu/Courses/ph12/index12b2007.html&lt;/a&gt;&lt;/p&gt;

<p>ME 18a:
<a href=“Mechanical and Civil Engineering”>Mechanical and Civil Engineering;

<p>This isn’t exactly “usual” though as most people take Ph 2 instead of Ph 12 and ACM 95 is listed as a junior class although many sophomores also take it.</p>
