GED Subject: Science

The Science section of the GED test can be one of the easiest subjects to study for if you understand the types of questions that will be covered. All questions will require the test-taker to read a short, informational prompt and then answer questions about it, with as many as four questions covering a single blurb of information. There are three major types of science covered by all the questions: earth sciences, life sciences, and physical sciences. These fields are related to each other, but recognizing the key differences will make it easier to study for each.

Life Sciences

Life science provides at least 40% of the questions in the Science section of the GED test. These questions will be related to biology and molecular chemistry, covering the basic principles of life and how it occurs. Not only is it important to know facts, but test-takers must also understand the concepts and principles beneath basic facts. Because life is a complicated system, this section of science relies on a web of interconnected ideas. The most common types of questions will be multiple-choice, fill-in-the-blank, drag and drop, and short answer.

Physical Sciences

Physical science, otherwise known as physics, is the second most important type of science to study for the GED test. This type of science accounts for approximately 40% of the test questions. Understanding physical energy and the mathematical principles that govern motion is essential to doing well on these questions. These questions will rely primarily on the short answer or fill-in-the-blank type questions, as they rely on calculations in most situations. Multiple-choice may also be used. This section of the Science test relies more heavily on mathematics than any other types of questions on the test. The computerized format of the GED test has an on-screen calculator to help with any calculations that need to be performed, but test-takers using paper must bring their own tools.

Earth Sciences

Earth and space sciences account for only 20% of the Science subject test on the GED. This section focuses on astronomy and planetary rules. Test-takers must be aware of the solar system and the distinct patterns that our planet follows throughout the year. Earth sciences are related to the environment and the many different seasonal, environmental, and biological changes that occur during different times on our planet. This section relies heavily on the fill-in-the-blank type of question, such as labeling parts of a system.
