GED Science: Exam Guide & Official Sources
Review the US GED Science format, then work through a daily plan for selected science reasoning skills.
Choose the comparison before judging the result
Build a fair comparison, then test whether the result can rule out a competing explanation.

32 suggested minutes
- Read both linked lessons and try their transfer checks (16 min).
- Answer the six linked questions and use the feedback (16 min).
- Use the linked cards or application guide for optional review.
Completion: Explain one answer with its evidence and check that you attempted all six questions.
If you need another pass: Revisit the relevant worked example. Name the condition you missed before trying a new item.
Compare changes with the correct denominator
Use axis labels and interval boundaries to choose between a value, a change and a rate.
