How our UPSC question bank is built
UPSC Prelims Test combines official previous-year question material with independent answers, explanations, and AI-assisted metadata. This page explains what comes from the exam, what we add, and how to report a problem.
2. Answer and explanation
Answer keys and explanations are independent study aids prepared with automation and AI assistance. They are not official UPSC answer keys and should be checked against official material when a final key is available.
3. Enrichment
AI-assisted classification adds topics, sub-topics, concepts, keywords, difficulty rationale, NCERT pointers, and memory aids. These labels improve discovery and practice, but they can contain judgment calls.
4. Quality checks
Automated structural checks and content audits flag malformed options, inconsistent keys, weak explanations, duplicates, and classification problems. The repository is reviewed iteratively; an audit flag is not a substitute for an official source.
5. Corrections
If you find an incorrect answer, year, subject, option, or explanation, send the question URL and the correction evidence. High-impact factual issues take priority.
