You cannot manually calculate your GED score because the GED uses a scaled scoring system developed by the GED Testing Service. Your raw number of correct answers is converted into a scaled score between 100 and 200 per subject using a confidential statistical process that accounts for question difficulty and exam version. Therefore, there is no public formula to calculate your GED score yourself.
After completing each subject test, your official score is posted to your GED.com account within 1–3 business days (or up to 24 hours for most tests). This score is final and cannot be recalculated by hand. The system automatically applies item weighting—meaning some questions (like the Language Arts essay or multi-part Science tasks) contribute more to your score than others.
How to Estimate Your Readiness Before Test Day
While you can’t calculate your GED score precisely beforehand, you can use the official GED Ready practice test ($6 per subject) to get a reliable prediction. GED Ready provides a scaled score estimate on the same 100–200 scale. If you score 150 or higher on GED Ready, you have a strong chance of passing (145+) on the real exam.
Do not rely on percentage-based guesses (e.g., “If I get 70% right, I’ll pass”). Because of scaling and question weighting, 60–65% accuracy may be enough to reach 145—but this varies by test form.
After your official test, your GED report will show:
- Your scaled score (100–200)
- Whether you passed (145+)
- Performance indicators by skill area
If you fall short, use this feedback—not raw question counts—to guide your retake prep.
The GED system handles all scoring objectively; your role is to prepare, not compute.
Trust the official score report—it’s the only accurate measure of your performance.
