I want to apply to graduate school for physics but I'm worried that my cumulative GPA might be too low. My GPA within the physics major is 4.0, but my cumulative GPA is 3.1. I started college in electrical engineering but wasn't happy in the major, and my grades were not very good. I have another year in college along with summer courses so I definitely have the time to improve that a little but I'm worried the damage may have been done. Would poor grades in engineering courses significantly hurt my chances of acceptance into a physics graduate program? Even if it was 2 years ago?
