That is what is says in the Cal Common Data Set, but I wonder if did it wrong. I’m guessing even though the instructions for the CDS say to count discussions separately, and even though Cal writes in the CDS they didn’t count them at all, that actually they rolled them into the CDS. Just for fun I went to the current schedule of classes for Econ at [UCB</a> Online Schedule of Classes: Search Results](<a href=“http://osoc.berkeley.edu/OSOC/osoc?p_term=SP&x=22&p_classif=U&p_deptname=Economics&p_presuf=--+Choose+a+Course+Prefix%2FSuffix+--&y=1]UCB”>http://osoc.berkeley.edu/OSOC/osoc?p_term=SP&x=22&p_classif=U&p_deptname=Economics&p_presuf=--+Choose+a+Course+Prefix%2FSuffix+--&y=1) and there is not a single lecture with 20 or less students enrolled. And these are the upper-division classes where you ought to find the smaller classes. Plenty of discussion sections in that range, though.</p>
