biology
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditar ...
. The test is comprehensive and covers—in equal proportions—molecular biology, organismal biology, and ecology and evolution.
This exam, like all the
GRE subject tests, is paper-based, as opposed to the GRE general test which is usually computer-based. It contains 194 questions, which are to be answered within 2 hours and 50 minutes. Scores on this exam are required for entrance to some biology Ph.D. programs in the United States.
Scores are scaled and then reported as a number between 200 and 990; however, in recent versions of the test, the maximum and minimum reported scores have been 940 (corresponding to the 99 percentile) and 400 (1 percentile) respectively. The mean score for all test takers from July, 2009, to July, 2012, was 658 with a standard deviation of 123.
Tests generally take place three times per year, on one Saturday in each of September, October, and April. Students must register for the exam approximately five weeks before the administration. ETS took the decision to discontinue the test after April 2021.
Content specification
Since many students who apply to graduate programs in biology do so during the first half of their fourth year, the scope of most questions is largely that of the first three years of a standard American undergraduate biology curriculum. A sampling of test item content is given below:
Cell and molecular biology (33-35%)
*
Cell biology
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living a ...

Metabolism
Metabolism (, from el, μεταβολή ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run c ...
*
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar worki ...

Microbiology
Microbiology () is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, ...

immunology
Immunology is a branch of medicineImmunology for Medical Students, Roderick Nairn, Matthew Helbert, Mosby, 2007 and biology that covers the medical study of immune systems in humans, animals, plants and sapient species. In such we can see ther ...
Organismal biology (33-34%)
* Animal anatomy and physiology

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic ('' genetic variability''), species ('' species diversity''), and ecosystem ('' ecosystem diversity' ...
