UPSC Prelims Answer Key 2025: Official PDF, Cutoff and Marksheet
UPSC released the official UPSC Prelims Answer Key 2025 on 13 May 2026. The set-wise PDFs cover GS Paper 1 and CSAT. The General cutoff was 92.66 out of 200, a sharp rise from 2024. This guide shares the official PDF links, category-wise cutoff, marksheet download steps and how to use the key for the 2026 cycle.
The Union Public Service Commission released two separate PDFs, one for General Studies Paper 1 and another for CSAT Paper 2 (GS Paper II).
You will find one PDF per paper, with all four question sets (A, B, C, D) covered. The numbering of questions changes across the four sets, but the questions themselves are identical. Set A is treated as the reference set.
The 2025 paper was widely seen as moderate to tough. Aspirants and coaching faculties flagged unconventional History questions, a longer Polity section, and a slightly easier Environment portion.
The CSAT paper was a fresh shock for many, continuing the pattern set since 2023. Roughly 5.83 lakh candidates wrote the exam out of around 13 lakh registered. Only about 14,627 cleared the cutoff for Mains.
UPSC does not release the prelims answer key right after the exam. The Commission waits till the entire CSE 2025 cycle is over and the final result is declared. For Prelims 2025, the timeline worked out as follows.

The Commission published the official cutoff on 9 March 2026, three days after the CSE 2025 final result. Persons with Benchmark Disability are abbreviated as PwBD.
Category | UPSC Prelims 2025 Cutoff (Out of 200) |
General | 92.66 |
EWS | 89.34 |
OBC | 92.00 |
SC | 84.00 |
ST | 82.66 |
PwBD-1 | 76.66 |
PwBD-2 | 54.66 |
PwBD-3 | Refer to UPSC PDF |
PwBD-5 | Refer to UPSC PDF |
The 92.66 figure surprised many aspirants. It was the highest General cutoff since 2020 (92.51). Two reasons explain the jump.
First, the GS Paper 1 was relatively more attempt-friendly compared to 2023 and 2024
Second, the candidate pool keeps getting better with every cycle, and the top of the score distribution has shifted upward.
The OBC cutoff at 92.00 sat just 0.66 marks below General. This near-overlap reflects the intense competition within the OBC pool, where the creamy layer rule keeps the eligible population smaller and stronger.
The UPSC Prelims 2025 marksheet shows your raw GS Paper 1 score, CSAT score and qualifying status. The Commission usually uploads marksheets about 15 days after the final result of the cycle.

Aspirant tip: Save your UPSC Prelims 2025 marksheet even if you did not clear the cutoff. It is the cleanest record of your raw score, useful for fee-waiver applications, scholarship forms and your own progress tracking over multiple attempts.
The answer key is more than a download. Done right, it shows you how UPSC frames its trickiest questions. Use it in five steps.
Solve the paper under exam conditions. Two hours, no break, no phone. Mark every attempt on a real OMR sheet copy.
Score yourself with the official key. Apply the marking scheme strictly. One-third deduction for each wrong attempt. Note any questions UPSC marked as dropped.
Slice the score by subject. Polity, History, Geography, Economy, Environment, Science and Tech, Current Affairs. Note where you bled the most marks.
Read the explanations for wrong answers. Lakshmikanth for Polity, Spectrum for Modern History, Shankar for Environment, NCERT Class XI Indian Economic Development for Economy.
Tag the source pattern of each question. Was it NCERT-based, scheme-based, current affairs, or a hybrid? Pattern recognition shrinks your blind spots faster than fresh study.
Aspirant tip: Do this drill in two passes. First pass with the unofficial coaching keys right after the exam, second pass with the official UPSC key after the final result. The gap between your two scores tells you exactly which questions sat on the borderline.
The table below puts the General category cutoff of the last seven prelims cycles in context.
Year | UPSC Prelims General Cutoff (Out of 200) |
2019 | 98.00 |
2020 | 92.51 |
2021 | 87.54 |
2022 | 88.22 |
2023 | 75.41 |
2024 | 87.98 |
2025 | 92.66 |
The 2025 cutoff completed a clear bounce-back from the 2023 low. For UPSC Prelims 2026 aspirants, this suggests the safe target should be 100 or above in mock tests, keeping a 10-mark buffer above the 2025 General cutoff.
The 2026 Prelims is scheduled for 24 May 2026. That gives you a clean window to plug the 2025 paper into your revision plan.
Three reasons make the 2025 answer key the single most useful PYQ resource for 2026.
First, it is the freshest signal of UPSC's framing style. The 2025 questions reveal which topics the Commission considers core, which it now uses as filler, and which formats (statement-based, assertion-reason, match-the-pair) it favours. Older papers carry good content but slightly stale form.
Second, the CSAT trend. The 2023, 2024 and 2025 CSAT papers all sat on the harder side. Treating CSAT as a free pass continues to knock out otherwise strong candidates. Read the 2025 CSAT carefully to understand the new difficulty floor.
Third, the cutoff jump to 92.66 forces a recalibration. Aspirants who built their mock-test targets around the 75.41 floor of 2023 are now sitting 17 marks below the actual 2025 cutoff. Reset your benchmark.
