Sources come first
When possible, we prefer an exam authority, official notification, statute, government publication, academic institution, or other primary source. A reliable secondary reference may be used to explain or cross-check a point.
What we check
- The question is complete and its options belong together.
- The marked answer agrees with a source or a reproducible calculation.
- Names, dates, units, formulas, scientific symbols, and translated meaning are readable.
- A doubtful answer is left blank for review instead of being presented as certain.
- OCR and encoding warnings are checked against the complete record or source.
Language and technical notation
Hindi matras, English text, other scripts, mathematics, reasoning content, and scientific notation can break during OCR or spreadsheet import. Automated warnings help us find unusual text, but a person decides whether it is actually wrong.
Report a factual problem
Send the question URL, the disputed text or answer, and your source through the correction form. We review evidence rather than the number of messages received.
