If I could have when I was in college, I totally would have just watched the 100+ people lectures online. If I wanted clarification office hours were always more useful, and most of my teachers and TAs were very pleasant to engage in that context. Thankfully most of my classes were more on the 20-30 person scale (all of them in CS) where attending felt much more valuable. The few 12 person classes I had were undoubtably the sweet spot though, with enough peers around to make discussion interesting but much more engagement between students and the professor. Not that I expect most classes to be at that size, it would just be a better world if they magically could be.
