<p>I don’t interpret it as a mistake to count discussion subsections.
Consider UCLA’s History 1A course (Western Civ).
It includes one 50 minute, 3x/week lecture that enrolls 229 students this Fall.
It also includes 14 discussion sections, each enrolling 6-20 students (totaling 229) and meeting 1x/week for 50 minutes. The 14 discussion sections should be counted as subsections, according to these CDS instructions:
</p>
<p>It appears that 5 TAs (grad students/lecturers) lead these 15 subsections. So on average, each would be responsible for grading ~46 students’ papers and exams.</p>
<p>Compare Macalester’s History 101 course (Intro to European History). It has one 90 minute, 2X/week class that enrolls a maximum of 25 students, taught by a single professor who received a PhD from UChicago in 2012.</p>
