The science section of the GED test is allotted 90 minutes to complete.
Three domains of science are tested, with the breakdown being:
- 40 percent Life Science
- 40 percent Physical Science
- 20 percent Space and Earth Science
Each of these domains are limited to two themes. The first theme is Human Health and Living Systems which includes physical characteristics of humans and other living things, systems of living organisms, the chemical and physical mechanisms by which the body works, and the interaction between living organisms and the environment. The second theme is Energy and Related Systems and includes sources of energy, how energy flows through ecosystems and organisms, and geochemical systems.
The questions are comprised of multiple choice, short answer, drag-and-drop, hot spot and fill-in-the-blank. The questions on the science test may involve scenarios including maps, graphs, charts or diagrams that inform several items related to the answer.
Even though there are numerous subjects covered on this section, test takers are not expected to have a mastery of scientific theories or subjects. Most of the questions involve common sense and expect a test taker to be able to use their general knowledge to answer scientifically-themed questions.
