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.
