What’s on the GED® Science Test?

What Does the GED Science Test Cover?

The GED Science test has three major components:
1. Life Science (40%)
2. Physical Science (40%)
3. Earth and Space Science (20%)

The two focusing themes of the GED science test are Human Health and Living Systems and Energy and Related Systems. Human Health and Living Systems involves concepts that are important to the health and safety of all living things. On the other hand, Energy and Related Systems discusses the most important parts of the universe. This theme includes energy sources, uses, and transformations.

Using a Calculator During the Test

For some parts of the GED science test, you will be allowed to use an on-screen calculator. Alternatively, you can also use a handheld TI-30XS Multiview Scientific Calculator. If you want to use the handheld type, make sure to bring it on the day you’re taking the test. You need to bring your own calculator. Otherwise, a calculator will automatically appear on your screen for questions that allow you to use one.
