GED Science Test (GED-SCI): Complete Exam Guide, Format, Topics, Scoring & Preparation

The GED Science Test (GED-SCI) is one of the four subject tests required to earn the General Educational Development (GED) credential. Administered by GED Testing Service LLC, the exam evaluates scientific reasoning rather than memorization of scientific facts. The official exam contains approximately 34–36 questions, lasts 90 minutes, requires a minimum passing score of 145, and costs approximately USD $36 per subject in many U.S. states, although fees vary by location. The exam is delivered by computer at authorized testing centers and is also available for online testing in eligible regions. It is intended for high school equivalency candidates and is offered primarily in English and Spanish, with additional accessibility accommodations available where applicable. Whether you are searching for a ged science test, GED Science practice test, or science ged questions, understanding the official exam structure is the first step toward success.

Exam Overview

The GED Science Test measures your ability to apply scientific concepts to practical situations rather than recall definitions or formulas. Questions are based on everyday scientific scenarios and require critical thinking, interpretation of graphs, reading comprehension, and evidence-based reasoning.

The exam focuses on scientific literacy through passages, charts, tables, illustrations, and experimental data. Candidates should be comfortable analyzing information and drawing logical conclusions from scientific evidence.
