I would say ML has blown up in the recent years. In addition to 189, all CS undergrads are now requires to take EE16A+B which, although focused on circuits, teaches a bit of linear algebra needed for ML; and some take in addition 126 (probability) and 127 (linear optimization). To add on to the parent comment, a 4 unit class is usually considered to have a 12 hour workload per week (180 hours a semester). [1] Two caveats to this: 1. There was controversy in the past from a CS professor that students should actually be putting in 20 hours per week [2]. 2. With some project or pset heavy classes, I don’t doubt that 20 hours was irregular. For example with 162 (operating systems), every week we had a tight schedule of lecture, discussion, homework assignments, group projects, and possibly a midterm to study for.
