Source hierarchy
When available, official notifications, statutes, government publications, exam authorities, academic institutions, and primary documents are preferred. Reliable secondary references may be used to explain or cross-check a topic.
Question and answer checks
- Confirm that the question is complete and options belong to the same question.
- Check the answer key against a reliable source or calculation.
- Review units, symbols, formulas, dates, names, and translated meaning.
- Leave the answer blank when a reliable single answer cannot be established instead of inventing certainty.
- Distinguish a factual correction from an opinion or exam-authority dispute.
Multilingual and technical content
Hindi, English, other scripts, mathematics, reasoning diagrams represented in text, and scientific notation require an additional legibility and meaning check. Transliteration alone is not treated as verification.
