The GRE physics test is an examination conducted by the Educational Testing Service (ETS). The tests try to determine the extent to which researchers understand the basic principles of physics and their ability to apply them to problem solving. Many graduate schools require applicants to take exams and basic acceptance decisions in part on the results.
The scope of this test is largely from the first three years of the US undergraduate standard physics curriculum, as many students who plan to continue to graduate school apply during the first half of the fourth year. It consists of 100 questions of five-choice options that cover subject areas including classical mechanics, electromagnetism, wave and optical phenomena, thermal physics, relativity, atomic and nuclear physics, quantum mechanics, laboratory techniques, and mathematical methods. The table below shows the relative weights, as confirmed by the ETS, and the detailed content of the main topic.
