Cluster 70B was an incredibly fun quarter where you revise aspects of evolution that you've learned before and also learn a lot of new information. Overall, content is decent, quizzes are biweekly and based on content taught in lectures. The class is recorded, and my favorite point is that there is no final exam, you submit a final paper after selecting a topic out of several choices at the end of the quarter. The paper is 4-5 pages, and double spaced. I enjoyed this class and would definitely recommend as a GE!
