Help make the learning material more accurate and easier to understand.
Suggest a primary source, report an unclear explanation or factual error, or identify a missing step in the story. A useful correction includes:
• Article URL and the relevant sentence;
• What should change and why;
• A source and its date, where available.
If a report contains private information, do not post it publicly. Use the site’s Contact page instead. Editors will distinguish confirmed corrections from open questions and record substantive article changes. A suggestion is welcome even if it challenges an editor’s interpretation.
