It has the highest pass rate of any GED test!
The test is 90 minutes long.
The GED Science test is a 90-minute, single section test. The test covers three major topics. These are Life Science, Physical Science, and Earth and Space Science.
You'll need to understand science concepts, know how to read graphs and charts displaying scientific data, and use reasoning to interpret science information.
The science test is not a memorization test! For example, on the Physical Sciences portion, you won’t need to memorize the periodic table of elements, but you will need to recognize names and symbols of some elements.
