One other difference here: a class forces you to keep moving when there's something you don't fully understand at the moment. And often that works pretty well --- you cover a bunch of ground imperfectly, and backfill the holes over time. It's easy to get a little bogged down without a teacher-equivalent tracking the pace, at least for me. Which also means I spend more time subjectively experiencing struggle than I would otherwise, regardless of how it's going objectively. Which I guess just maps to "increased decision-making caution" in the paper.
