The most dangerous assumption in UPSC preparation is that GS Paper 1 has a fixed composition. It does not — but the way it shifts is not the tidy "this subject is rising, that one is falling" story most strategy notes tell. Four years of tagged data shows a few genuine directional signals and a lot of year-to-year volatility, and telling the two apart is what actually informs how you allocate your time.
The four-year picture
GS Paper 1 — question count by subject, 2022–2025
What actually eased
Economy and Environment — off their 2022 highs
The two subjects that were largest in 2022 have both drifted down. Economy went from 18% in 2022 to 12% in 2025; Environment from 17% to 12%. Neither has collapsed — both remain firmly in the mix — but the assumption that they are "growing" is not supported by the data. What has changed is their texture: more application-based, more often tied to a current development.
International Relations — the genuine thinner
IR is the one subject with a clear downward drift — from 11% in 2022 to 5% in 2025. It has not vanished, but its weight is lower and increasingly blurred into Geography and Current Affairs rather than standing alone.
What held strong or climbed
Polity — the one durable riser
Polity climbed from 12% in 2022 to a peak of 20% in 2024 before easing to 18% in 2025 — the most reliable heavyweight in the paper across the cycle. See our dedicated Polity analysis for the full breakdown.
Current Affairs — a category that emerged
Explicit Current Affairs barely registered as a tagged category in 2022 and accounted for 10% of the paper by 2025. This is the clearest new signal in the dataset — the paper increasingly rewards candidates who track the year's developments.
What just bounces around
History, Geography, and Science & Technology show no clean trend — they swing year to year. History fell to a low mid-cycle and recovered to 16% by 2025; Geography peaked in 2024 then fell back; S&T moved within a narrow band. Treating any of these as "rising" or "declining" over four data points reads more into the numbers than they support.
Spotlight: the four-year shift in detail
The shifting subjects — Polity climbing and Current Affairs emerging; Economy easing; History volatile
What this means for your 2026 preparation
Strategy note
Don't chase single-year swings. The honest signal from four years of data is volatility, not clean trends. The defensible moves: keep Polity as a load-bearing priority (the most consistent heavyweight), and build a genuine Current Affairs habit (the clearest emerging category). Beyond that, broad, balanced coverage beats trying to time which subject is "rising".
Strategy note
Maintain coverage of History and S&T rather than deprioritising them. Both swing widely year to year — History fell to a low one year and rebounded the next — so a year of low weight is not a reason to cut depth. The risk in over-optimising is being caught out the year a subject bounces back.
Data note
This analysis covers 2022–2025 — four data points. Trends drawn from four points are directional at best. Use this data to inform emphasis, not to eliminate any subject. Every subject has a floor of at least 5–6 questions in a typical year; nothing is safe to skip entirely.
