The GED Science is the official GED exam that leads to the GED High School Equivalency Credential certification at the High School Equivalency level. Passing it validates your skills against GED standards and proves your qualification to current and future employers. The credential is also connected with related certifications such as GED Reasoning Through Language Arts, GED Mathematical Reasoning, GED Social Studies, so it can serve as a solid step in a broader certification path.

The GED-Science exam has 34–50 questions in total and must be completed within 90 minutes. That leaves only a narrow time budget per item, so train yourself to flag a difficult question, move on, and circle back later instead of getting stuck. A week or two before your test date, run at least one full timed mock exam in the iPassleader desktop or online test engine under the same 90 minutes limit, and repeat until you can finish with a few minutes left for review.

The passing score for the GED-Science exam is 145 (scaled score 100–200), and the official registration fee is USD $30–$90 (varies by region; international approx. $85). Keep in mind that a failed attempt is not discounted — retaking the exam means paying the full fee again — so it is wise not to book your seat until your practice scores sit comfortably above the passing mark. Working through the 300 questions at iPassleader in timed mode is a reliable way to judge when you are truly ready.

GED sets the following requirement for the GED-Science exam: Not enrolled in high school, not a high school graduate; minimum age 16–18 (varies by jurisdiction); valid government-issued photo ID required.
