GED Science Test

GED® Science TestWhat’s on the GED Science Test?

To score well on the GED® Science Test you need to be able to understand, interpret, and apply scientific information.

Data will be provided in reading texts, graphs, charts, diagrams, tables, maps or a combination of these. You need to use your reasoning skills to interpret science information.

The GED® Science test covers three main categories:

1. Life Science (40%)
2. Physical Science (40%)
3. Earth and Space Science (20%)

The test is 90 minutes with no breaks.

Many scientific processes use mathematics. When required, an on-screen calculator will be provided. You will also be given a white board and marker to use for any rough calculations.

The GED® Science Test is not a memory test. You will not have to study parrot-fashion and cram memorised facts and information the night before the GED® Science Test. The aim of the test is to evaluate your skills. You do not need to memorise laws, definitions or information like the entire period chart, but you need to recognise names, symbols and key elements.


The three main categories will cover the following content areas:

Life Science includes the structure of cells and their processes and functions, human life and body functions, nutrition and energy intake, genetics and DNA, reproduction and heredity, evolution and natural selection, and the organization of ecosystems.

Physical Science topics include energy flows and conservation, work, motion and forces, atoms and molecules, properties and states of matter, chemical properties and reactions, waves, electricity, and magnetism.

Earth and Space Science focuses on the solar system and the universe, the geological structure of the earth, plate tectonics, geological cycles and processes, renewable and non-renewable natural resources, weather and climate, the relationship between the earth’s structure and living things etc.
