Math graduate, not enough physics coursework to apply straight to physics MS I have a BS in math (2.9) and a MA in teaching (Pass/fail online program)
I am teaching math at a high school but now miss my college days and the upper level material. My end goal would be a PhD in Physics at a US university.

I don't have enough course work in Physics to try and apply straight to a Masters in Physics, as well as a low GPA to apply with.

What are my options? (I have ideas but am unsure as to what is realistic or worth doing)
Community college classes until I have prerequisites for physics?
Non-matriculated schooling?
If you are studying in the United States, you should take the core physics undergraduate courses from a reputable university.  Then you should apply directly to PhD programs.
