I want to take PChem, but I'm wondering if I should wait until I have a deeper understanding of quantum mechanics and electricity and magnetism. I've seen QM in a modern physics class and I've taken a sophomore level E&M class. I've got my calculus down pretty well, and I've taken two semesters of gen chem and two of Ochem. Any advice on recommended background would be appreciated. I'm looking to get as much out of the class as possible (and to also not struggle the whole way through), so I'm not opposed to waiting a few semesters. I do have an opening in my upcoming schedule, however, so I thought that I should do it if I'm ready. Thanks.
