Required class for the major/minor, so you'll most likely have to take it. DOn't take it for the science requirement, it's a lot of work. But you learn an incredible amount, so defintely worth it if you're interested in the topic. Kushnir has an accent, talks softly, but his slides are good. Gordon was better than Kushnir, but tended to go off on tangents about Antarctica and Malaysia. He's a hard grader. Hays was the best professor because he explained the most and took the time to answer questions well.
