We are now offering a physics GRE study session for SPS members. If you're interested, please send an e-mail to SPS president Adam Catching, or sign up in physical sciences 110.

We meet every Saturday at 3pm in Physical Sciences 106.

The test consists of approximately 100 five-choice questions, some of which are grouped in sets and based on such materials as diagrams, graphs, experimental data and descriptions of physical situations.

The aim of the test is to determine the extent of the examinees' grasp of fundamental principles and their ability to apply these principles in the solution of problems.

Most test questions can be answered on the basis of a mastery of the first three years of undergraduate physics.

The International System (SI) of units is used predominantly in the test. A table of information representing various physical constants and a few conversion factors among SI units is presented in the test book.

The approximate percentages of the test on the major content topics have been set by the committee of examiners, with input from a nationwide survey of undergraduate physics curricula. The percentages reflect the committee's determination of the relative emphasis placed on each topic in a typical undergraduate program. These percentages are given below along with the major subtopics included in each content category. In each category, the subtopics are listed roughly in order of decreasing importance for inclusion in the test.

Nearly all the questions in the test will relate to material in this listing; however, there may be occasional questions on other topics not explicitly listed here.
