Calculating Your Score
UPSC Prelims uses a penalty system for incorrect answers, so calculate your General Studies and CSAT scores carefully, accounting for negative marking, rather than simply counting correct responses.
Challenging an Answer
UPSC typically does not offer a public challenge window like some other exam bodies, so most candidates rely on trusted coaching institutes’ analysis to identify any genuinely debatable questions before finalizing their self-assessment.
Frequently Asked Questions

Q: How accurately can I predict my Mains eligibility from Prelims marks?
Comparing your estimated score against previous years’ cutoffs gives a reasonable indication, though exact cutoffs vary each year based on difficulty level.
