The GRE (Graduate Record Examination) subject tests are supplemental to the general GRE examination taken by many graduate school applicants nationwide. Though not usually required as part of the admissions application to graduate school, taking a GRE subject test can benefit an applicant, especially if he is pursuing a graduate degree that corresponds with one of the eight subject tests. Regardless of the applicant’s subject test score, attempting one of the tests shows dedication to the subject and to the school.

*GRE subject tests are currently offered in the following six areas:*

1. Biology

2. Chemistry

3. Literature in English

4. Mathematics

5. Physics

6. Psychology
