Topology is hard. And the final exam is really hard, definitely nothing like what is in class. Since the textbook (Munkres -- pretty much the only topology textbook in existence) is created for a two-semester graduate school course, and this class covers it in one semester as a 300-level course, you have to skip a lot, so it's hard to know what to review in the textbook. Also, there are very few examples, and a lot of long proofs, and almost no illustrations.
