About the GED Science Exam
The GED Science test is a 90-minute computer-based exam covering approximately 34–40 questions across Life Science (40%), Physical Science (40%), and Earth and Space Science (20%). Questions use multiple-choice and technology-enhanced formats; short-answer items were eliminated in 2018. The exam emphasizes reading and interpreting scientific passages and data, not just memorized facts. A score of 145 or higher (on a 100–200 scale) is required to pass.
Exam sponsor: GED Testing Service (Pearson/GED joint venture). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

How do the GED Science vocabulary games work?
There are 4 games built on 20 GED Science terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the GED Science terms come from?
OpenExamPrep researched each term from the GED Testing Service (Pearson/GED joint venture) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
