<p>Apart from CS16, the large CS classes do not break into sections (4, 15, 17, 18, 22, 31, 157 this year). Some of them have labs, some do not, which you may consider to be similar, though all of my CS classes with labs did not require us to attend the actual lab, just do the work for it and get it checked off during TA hours. 31 offered a single optional review session a week because I felt it was a good idea, but it was not required and the size wasn’t capped - some reached 50 people for a class of about 120.</p>
<p>A number of the applied math classes exceed this size and offer 1 informal optional review session a week (120 and 165, for instance, though I suspect that this depends on the professor).</p>
<p>The math department is good about having sections for their large (100+) classes. Econ seems to as well.</p>
<p>If we reduce the size in question from 100 to 50, this now includes many intermediate math courses and any classics course that exceeds that size (normally only history and mythology), as far as courses I’m aware of. I couldn’t begin to guess about courses like abnormal psychology (upper level psych class that’s generally over 100) or mid-level science classes, but there are definitely classes in multiple departments that don’t break into sections anything like the ones mentioned, TA-led or otherwise.</p>
