In paper-and-pencil tests, the differences in difficulty among test forms are relatively small and are adjusted through a process known as score equating. The number of questions answered is also figured into the calculation of the reported score because it limits the number that can be answered correctly. Scoring of the tests is a two-step process.
- First, a raw score is computed. The raw score is the number of questions you answered correctly minus one-fourth the number of questions you answered incorrectly.
- The raw score is then converted to a scaled score through a process known as equating that accounts for differences in difficulty among the different test editions. Thus, a given scaled score reflects approximately the same level of ability regardless of the edition of the test that was taken.
Score Scales for the GRE Subject Test
One total score is reported on a 200 to 990 score scale, in ten-point increments, although the score range for any particular test is usually smaller.
Subscores are reported for the biochemistry, cell and molecular biology; biology; and psychology tests on a 20 to 99 score scale, in one-point increments, although the range for any particular test subscore is usually smaller.
