I’m teaching 3 sections of the same class this semester, as well as running workshops for a bunch of other classes (being full-time teaching faculty = being very very busy!). Trying to keep my course sections straight is kind of a nightmare – there’s no logic to the order the classes occur in relative to their recitations relative to the CRN (the numbering system we use) and they’re in weird rooms and it’s making my brain hurt. Color-coding to the rescue!
