This was a fun class. However, the TAs were very strict about grading in weekly homework sets. You would lose random points because it seems unclear each time what they're expecting from your answer. There were 4 midterms, all of which were fairly difficult because the class average was 75% each time. I think it's because we were quizzed on niche facts glossed over in class. Lectures were mandatory with iClicker. There was a handful of extra credit opportunities to make up for missed attendance, and we even had a field trip to the Natural History Museum in LA that counted as a discussion session. TLDR: stressful class with hard exams and mandatory attendance.
