8. Key Caveats
-
- This analysis is a preparation aid, not a guarantee — UPSC frequently innovates question framing even on recurring themes; treat ‘expected topics’ as priority areas for depth of preparation, not spot-guessing.
- The LWE ‘elimination’ declaration (March 2026) and the exact tariff percentages in the India-US trade deal are both contested/variably reported in sources — treat these as claims to be critically examined in an answer, not settled facts to state uncritically.
- Sub-topic counts for 2013–2019 rely on a secondary compilation (marks/word-count data was largely unavailable for that period in the source used); your own Lukmaan baseline, where it has real marks data for those years, should be treated as the more authoritative source for exact marks in 2013–2019.
- Money laundering (2 questions in 13 years) and security-forces’-mandate content (embedded in broader questions, never standalone) are the thinnest, lowest-confidence sub-topics — treat their low rank with some caution rather than as a signal to skip them entirely, especially given money laundering’s rising real-world salience (crypto, hawala).
- The current-affairs pipeline (Section 6) is current through approximately mid-2026; developments in the final 1–2 months before the exam are not captured and should be checked separately.
