Is UPSC Prelims Getting Harder?
Short answer: yes and no. From 2015 to 2026, easy-question share fell from 42% to 11% — the paper genuinely got harder. But 2026 rebounded to 11% easy. Hard-question share has stayed in a narrow 3–25% band throughout. Full year-by-year below.
The actual trajectory
| Year | Easy | Moderate | Hard | Total | Easy % | Hard % |
|---|---|---|---|---|---|---|
| 2015 | 33 | 40 | 5 | 78 | 42% | 6% |
| 2016 | 44 | 38 | 9 | 91 | 48% | 10% |
| 2017 | 39 | 41 | 5 | 85 | 46% | 6% |
| 2018 | 35 | 41 | 7 | 83 | 42% | 8% |
| 2019 | 32 | 44 | 5 | 81 | 40% | 6% |
| 2020 | 36 | 41 | 2 | 79 | 46% | 3% |
| 2021 | 32 | 40 | 5 | 77 | 42% | 6% |
| 2022 | 28 | 50 | 8 | 86 | 33% | 9% |
| 2023 | 28 | 44 | 9 | 81 | 35% | 11% |
| 2024 | 35 | 38 | 7 | 80 | 44% | 9% |
| 2025 | 31 | 42 | 7 | 80 | 39% | 9% |
| 2026 | 11 | 63 | 25 | 99 | 11% | 25% |
The common narrative — "UPSC keeps getting harder every year" — is half right. The data shows a clear hardening trend from 2015 through about 2026, then a slight easing in 2026. Not a straight line.
Easy-question share peaked at 48% in 2016, bottomed at 11% in 2026, and recovered to 11% in 2026. Net 2015→2026: a 31-point decrease in easy share.
What actually changed
The real shift isn't in hard questions — hard share has hovered in a narrow 3–25% band every year. What shifted is the moderate tier: questions that aren't outright hard but require careful elimination, trap-awareness, and second-order thinking. Moderate climbed from 51% in 2015 to 64% at its peak.
In practical terms: UPSC hasn't been adding obscure facts. It's been adding traps. The well-prepared aspirant who could coast through 40+ easy questions in 2015 is now navigating 50+ moderate questions where option elimination is the differentiator — and where our trap analysis actually matters.
What this means for your prep
Don't over-index on impossible questions.Hard share is small and structurally stable. If you can't crack 25questions a year, you're not alone — most aspirants can't. Leave them.
Do over-index on the moderate tier.That's where Prelims is actually decided. 50 questions a year, each with a trap designed to catch aspirants who have memorised the fact but not practised elimination. This is exactly what subject-wise PYQ practice with trap analysis is built for.
What this doesn't tell you
Difficulty is not the same as predictability. A year can have more "moderate" questions yet still be more predictable if the topic mix is conventional. For the topic-mix cut, see most-repeated topics. For mock calibration against these distributions, see our mocks — each labelled with its intended difficulty spread.
Difficulty labels (easy / moderate / hard) are reviewed by UPSC aspirants and the PYQLabs community. They reflect expected accuracy for a well-prepared aspirant, not raw fact obscurity.
