If you are getting ready for the GED exam, you are required to understand the Science portion of the GED Science test. The three broad topics include life science (about 40% of the test),  physical science (about 40% of the test), and Earth and space science (about 20% of the test).

Within these three topics, all items fall within one of two themes:  human health and living systems, and energy and related systems.  So check what you know with our practice tests.

Our free GED® Science practice test include the following topics: Life Science, Space Science, Earth Science, Physics and Test Strategies, and Chemistry.

GED Life Science

Life Science deals with Living Systems and Human Health. You will be assessed on your knowledge regarding the safety and health of everything that lives on our planet. Space Science is about the universe we are living in, our Earth is part of a solar system that contains the Sun and nine planets.

GED Physics

GED Physics and Test Strategies. Physics is the science that is revolving around studying energy, and in what way we can apply this energy to get things done.

GED Chemistry

Chemistry studies the world of Matter & Energy. Chemistry is, just as physics, a physical science and it researches and explores structures of energy and matter, and in what way these two are interacting.

GED Space Science

Studying for the Space Science section of the GED Science test will teach you how to answer to questions such as “What is the speed of light in miles per second?”, “Which one is our solar system’s largest planet?”, or “Which science is dealing with the outer space studies?” To be successful at this portion of the GED exam, you need to be able to read and understand charts and graphs as well.

Physical Science (Physics & Chemistry) takes up around 35 percent of the Science test, so understanding the matter is crucial. You will be taught how gravity works and why it is that the closer we get to the surface of the Earth, the stronger the force of gravity gets. The force of gravity is measured in Newtons (or N), and is much stronger when we are on the surface of Earth than when we find ourselves thousands of miles above Earth. You will learn why that is.

Applying the right strategies may increase your GED score, and practicing smart exam-taking tactics you will enhance your score. You can use our GED online video lessons that provide you with tips for guessing intelligently, how to plan your time, and the best ways to review your work.

Around  40 percent of the GED Science test is about life science, another 40 percent deals with physical science, and roughly 20 percent consist on questions related to Earth and space science.

The most recent version of the GED exam was introduced in January, 2014, and this time the program, that enables adults to earn a credential equivalent to a high school diploma, had gone through the most significant overhaul in its seventy year history. The entire exam (four tests that can be taken separately within a 2-year time frame) is computer-based. All four tests are measured on a 100 – 200 points scale and the minimum required number of points you need to score on each test is 150.

If you score is 170 – 200 points on every one of the four tests, and your total result is no less than 720 points, you earn a GED Honors diploma. If your score is below 150 points, you usually can retake that test two times without a waiting period, but in case you need to take a third retest, the standard procedure is that you will need to wait 60 days before you can take the test again. Rules and regulations vary by state, though, so please check with a prep or testing center near you to be sure!

There’s no need to prepare for all areas at the same time, you can prepare for and take one test at a time, and you’ll have two years for completing the entire battery of GED tests.

The level of skills and knowledge needed to be successful at the GED exam may be compared to that of high school graduates. The GED credential is across the nation accepted as equivalent to a standard high school diploma by practically every employer or institution of higher education. You now have the option to take one of the four tests at a time, and your test results will stand for two years. Prepare for one test, pass it, and move ahead towards the nest test (also referred to as a ‘module’). This is actually one of the greatest improvements of the latest edition of the GED exam which was implemented in the beginning of 2014.
