I'm currently a master's candidate in math at a middle tier university in the USA. I studied math/physics during my undergraduate outside of the USA. I'll be looking to move to a different program after picking up my master's in a years time. My interests are inter-disciplinary, and I'm a bit interested in mathematical physics as well. I will, however, most likely sit for the Math GRE exam, and I will probably not have enough time to study for the Physics GRE from the scratch. Are there any good (theoretical) physics programs that don't require the physics gre? If not, I'll probably look at math programs that have people working on this front.
