I have been wondering if I should take Graduate level QM as an undergraduate. I'm currently signed up for a two quarter QM series, I have already taken a one quarter introduction to QM. I am a bit apprehensive as I am unsure if they assume vast QM knowledge (which I would sort of expect seeing as it is a Graduate level). One plus side is that I know a few others that are taking this course as well which would enable me to form a study group, which would obviously aid in learning more. I would like to take a full year of Graduate level quantum mechanics because so far I really enjoy the material, at least what I have taken in the introduction course, and taking this series would allow me to pursue QFT my senior year. I ultimately want to go to graduate school for Astrophysics, where I doubt I would be introduced to QFT.
