I really liked this subject, it is mostly about green energy/sustainability/education keywords, and the actual course material is relatively easy. But man is the grading strict, and the workload is harsh. You have to practically write 2 different completely distinct papers on some sort of sustainability topic, one personal and one for the group project. If your group members are disinterested, you also get less points. And by god, if you miss in class or online discussions more than twice, your grade will tank hard. Speaking of the essays, you have to write 2.5 1500 word different essays for this class. The last one is an edit of the 2nd one, but it often might as well be a whole new essay. And you must use one of the reading material sources. My suggestion is to read one of them and base your entire essay of off that one, use other sources as just a compliment. Or shodily at a reference at the last minute like I did. Overall, liked the course, but it's not for everyone
