GRE® Subject Matter Test in Literature in Biology

Completing the GRE® Subject Matter Test in Biology will help the prospective graduate student showcase his or her knowledge and expertise in upper division Biology subjects.

All GRE® Subject Matter Tests are accepted at most colleges and universities and offer additional standardized information about the applicant. While a Subject Matter Test may not necessarily be required for admission, an exceptional score in a certain subject can serve to elevate the student’s summary and records during the graduate admissions process.

The GRE® Subject Matter Test in Biology contains approximately 190 five-choice questions and is assembled into 3 divisions: ecology and evolution, cellular and molecular biology, and organismal biology.

Each of the three parts is accorded equal weighting on the test scoring (approximately 33 to 34% for each part), but each part may not necessarily consist of exactly the same number of questions.

Some of the questions will utilize diagrams, experimental results, and laboratory and actual situations and will be in groups of questions near the end of the test. These questions will be grouped together by subject and the evidence used for the pool of questions.

Questions may require the interpretation of quantitative mathematical models. While certain principles of the three parts may be assumed to be interconnected, some questions may consider sensitivities to existing environmental concerns. Students will be awarded a total test score and also three subscores, one for each of the three different divisions of the test.

  • Part One, cellular and molecular biology, includes questions on: cell structure, function, compounds, enzymes, membranes, cell surfaces, organelles, cytoskeletons, cell cycles, and growth; genetics and molecules, chromosomes, genomes, gene expression and regulation (mechanisms and effects), immunobiology, viruses, bacteriophages, and recombinant DNA.
  • Part Two, organismal biology, consists of questions relating to animal and plant structure, function, organization, development, reproduction, growth and behavior; diversity of life, archaea, bacteria, protista, fungi, animalia, and plantae.
  • Part Three contains questions regarding ecology: environmental organism interaction, behavioral ecology, populations, structures and functions, communities, ecosystems; and evolution: genetic variability, evolutionary processes, and consequences as well as history of life.

While the test is lengthy, no student is expected to be familiar with all subject matter or be able to answer all questions correctly. Many short, multiple choice questions, along with the lengthy scope of the test, have been proven to work to the student’s advantage in allowing the student to fairly, accurately, and systematically evaluate his or her knowledge of the test material. The student may obtain a maximum score on the GRE® Subject Matter Test in Biology without actually answering all the questions correctly.
