The syllabus describes the exam; the past papers are the exam. Every real question is a sample of how UPSC thinks — what it considers worth asking, how it phrases a trap, where difficulty actually lives — and a few years of papers teach that faster than any amount of advice. This archive holds them year by year, exactly as the hall received them.
The grid runs from the current cycle back to 2013, the first year of the present Mains pattern. Each year’s tile lights up when its page ships.
The archive, year by year
What each year carries
A year’s set is the seven papers every candidate shares — the whole of Prelims and the compulsory core of Mains. Optional-subject papers and the two qualifying language papers are not archived; the forty-eight optionals belong on UPSC’s own site, and the language papers count nothing toward merit.
- GS Paper I (Prelims)
- CSAT (Prelims)
- Essay
- GS Paper I (Mains)
- GS Paper II (Mains)
- GS Paper III (Mains)
- GS Paper IV (Mains)
Working a paper properly
A past paper has exactly one first sitting in it. Spend it well: the full paper, the real clock, and the exam’s own scoring — two marks for a right answer, a third of that back for a wrong one, nothing for a blank. Only then read the solutions, and read them hardest where you were confidently wrong.
The Mock Tests section runs that routine for you, timer and scoring included; the cut-off marks turn the resulting number into a verdict.
Past papers — common questions
Which papers are in each year’s set?
Seven: both Prelims papers — GS Paper I and CSAT — plus the Essay and the four General Studies papers from Mains. That is the shared spine of the exam; every candidate in the country sits all seven.
Why no optional-subject or language papers?
Forty-eight optional subjects at two papers each would swamp the archive with papers only a small fraction of readers ever sit, and UPSC’s own site carries them. The two language papers are qualifying at 25% and count nothing toward merit, so they teach little as practice material.
Why does the archive start at 2013?
That is the first year of the current Mains pattern — the Essay plus four General Studies papers. CSAT joined Prelims earlier, in 2011, but pre-2013 Mains papers follow a retired structure that no longer maps onto preparation.
Are official answer keys included?
UPSC publishes its official Prelims key only after the entire cycle ends, typically around the final result the following year. Year pages carry the papers first and the official keys as they are released; treat the coaching keys that circulate in exam week as provisional — they disagree with each other every year.
What is the right way to use a paper?
Whole, timed, and scored to the exam’s own formula before any solution is read. A paper browsed casually is spent — it can never again tell you what an exam-day attempt would have scored. Sit it, score it, then give the review more time than the sitting took. The Mock Tests section exists to make that routine effortless, and the cut-off marks tell you what a score means.
