Both the General GRE and the Physics Subject Test GRE are required for admittance into a Ph.D. or Master's Degree program for physics. The General GRE is offered all year long and the Physics GRE is offered only in April, September, and October. Most physics majors take the Physics GRE September or October of their senior year. Students can register for either test by going to the GRE website.
