So I need to decide by tomorrow, whether I'll be taking topology or diff geo, (along with real analysis and advanced linear algebra). I've sat in on both classes for the first lecture, and I'm still not certain which class would be more difficult. My diff geo class has no exams, and instead requires a presentation and an expository paper at the end of the semester. Anyone know what that might entail? Topology is, however, the typical problems sets and exam format. I feel like I'm already overloading on my math classes, so I would like your opinion on which class to take.
