I'm a physics major who's interested in geophysics. I'm planning to go to graduate school for either physics or geophysics, but I seem to be leaning more towards physics. I've got a year or so to figure this out so I've been talking to professors, one of which is a physics PhD in the geology department. He suggested that I go for a geology minor regardless so that's what I've been shooting for. The problem is, I probably won't be able to take quantum II (second half of Griffiths) if I go through with the minor. I'm worried that without quantum II, I'll be less competitive for physics grad programs, but without the geology minor I won't be as competitive for geophysics programs. Is having quantum II as an undergrad necessary for physics grad school even if I'm going to do research in geophysics? Appreciate the help.
