Subject-Specific GRE Tests

GRE subject tests evaluate an individual’s specific knowledge in an academic field of study. Subject test scores may be submitted to grad schools as a supplement to the general test score reports, or independently without a general test score (entrance examination requirements will vary by institution). GRE subject tests are rarely required for admission into graduate-level programs, but thousands of institutions still take subject scores under consideration during admissions .

Currently, there are seven GRE subject tests offered in the U.S. This includes: (1) Biochemistry, Cell, and Molecular Biology, (2) Biology, (3) Chemistry, (4), Literature in English, (5) Math, (6) Physics, and (7) Psychology. The data below illustrates how each of the seven exams is structured. For a more detailed breakdown of the content structure of each subject test, visit the ETS website (linked in each section).

Unlike the general test, GRE subject tests are only available in the paper-based format. To register for a subject test, applicants must first create a My GRE account. All seven subject tests are offered three times a year: April, September, and October (specific dates vary, but tests always fall on a Sunday). At the time of registration, test-takers can decide on the best month for their subject exam. Online registration is not available for test-takers requesting accommodations or Fee Reduction.

All GRE subject tests are scored on a weighted scale of 200 to 900 in 10-point increments, with the exception being the Biochemistry, Cell, and Molecular Biology exam, which is scored on a subscore scale of 20-99 in one-point increments. All scores are valid for five years after the testing date, and exam-takers will have the same score reporting options (including ScoreSelect) as the general test-takers (see this section on scoring).
