Reporting an error
Choose “Content correction” in the Rights & Contact form. Include the page URL, question or passage, current text, suggested correction, and a reliable supporting source.
Review process
A reviewer compares the report with available sources and the surrounding context. We may ask for clarification. A disagreement is not automatically an error, especially where an official exam key is disputed or multiple interpretations exist.
Material corrections
When a significant error is confirmed, the answer, explanation, translation, date, or other affected content should be corrected promptly. The page update time may change. Minor spelling or formatting fixes may be made without a separate notice.
Transparency
We do not promise that all historical material is error-free. We do promise to provide a practical reporting channel and a human review process for credible evidence.
