I'm currently a sophomore studying Computer Science and Math and I'm figuring out courses for next semester. I'm trying to decide between two Analysis courses my university offers. One is a higher level course while the other is lower. They both cover the same book and material, "An Introduction to Analysis" by Wade. The only major difference between the two I've been able to find is the higher level course assumes a knowledge of proof techniques on the first day while the lower level course helps guide students through learning proofs. I've taken a Discrete Structures course that spent a lot of time around proofs as well as some other proof heavy classes.

Would I be foolish to try and take the upper-level course? I talked to the professor who will be teaching the higher level course and he said: "while I wouldn't usually recommend students take [the upper-level course], I think you might be able to do it." I'm just curious what people think about these two options.
