Hello all, I'm a junior math major at uc Berkeley. And I'll be applying to physics Ph.D. programs. I have taken almost all required physics undergraduate courses, and have already finished about six graduate physics courses. And I got A on all of these classes. I expect myself to finish more graduate physics courses later on. Besides that, I've done plenty of math undergrad and grad courses with special focus on geometry, with A on all these. But I haven't done any lab courses, and I don't think I'll have time to take these courses in the future. Also, I haven't really worked in a research group before. I'm just wondering if all these graduate courses help my grad school application. And will I be able to get into a decent physics program with only a math major?
