UPSC Prelims 2025 Exam Analysis: Section-Wise Breakdown

The UPSC Prelims 2025 exam brought a mix of surprises and familiar patterns, offering candidates a slightly more approachable paper compared to previous years. Nearly 50% of the questions were categorized as easy, making the paper notably more accessible for well-prepared aspirants. However, the shift in subject weightage and difficulty levels reveals interesting insights into UPSC’s evolving strategy.

History & Art & Culture (16 Questions):
This section was a breather, with many straightforward questions, especially from Modern Indian History. Topics ranged from the Independence Struggle, Raja Ram Mohan Roy, and Fa-Hein, to lighter surprises like fruit origins and the Indus Valley’s ‘Dancing Girl’. Buddhism, a usual favorite, was notably absent.

Polity (12 Questions):
One of the most notable trends was the dominance of Indian Polity and Science & Technology, both contributing 16 questions each, the highest among all subjects. While Indian Polity has traditionally been a core area, Science & Technology’s equal representation underscores its growing relevance in the current affairs-driven landscape of the UPSC exams.

Economy (17 Questions):
This section was concept-heavy with a touch of arithmetic, featuring topics like RBI, fiscal deficits, RTGS, UPI, green economy minerals, and investment tools. The mix of static and current topics tested candidates’ understanding of real-world economics.

Science & Tech (15 Questions):
Interestingly, while Science & Technology had strong representation, it also featured the highest proportion of difficult questions, presenting a challenge for those relying only on basic NCERTs or static resources. Meanwhile, History made a comeback, with a noticeable increase in the number of questions—signaling a renewed focus on historical understanding, especially in modern and ancient Indian contexts.

International Relations (5 Questions):
Focused mainly on global groupings like BIMSTEC, BRICS, INSTC, and NATO. Mostly easy, except a curveball on the EU’s Nature Restoration Law.

Miscellaneous (7 Questions):
Another significant trend was the heavily current affairs-oriented Miscellaneous section, which comprised 18 questions. This indicates that UPSC continues to emphasize dynamic content, urging aspirants to stay consistently updated with national and international developments.

Geography + Environment (28 Questions):
In contrast, Geography witnessed a decline, with the number of questions dropping from 16 last year to just 12 this year. Similarly, the Environment section saw a reduction, with only 9 questions—the lowest among the major subjects, despite its usual prominence due to current environmental concerns and climate-related policies.

UPSC CSAT 2025 – Emerging Trends

The UPSC Prelims 2025 showcased a clear shift towards an integrated approach, where subjects like Polity, History, and Environment were no longer siloed but interconnected. Questions required an understanding of how one topic influences another, demanding a holistic preparation strategy.

There was a noticeable rise in application-based questions, testing candidates’ practical understanding rather than rote memorization. This trend emphasized the need for conceptual clarity and the ability to apply knowledge in real-world scenarios.

Current affairs continued to dominate, but with a twist — many questions from traditional subjects like Economics and Science were rooted in contemporary issues, showing the commission’s intent to assess awareness of the present-day context.

Finally, analytical thinking took precedence. Candidates were expected to go beyond mere factual recall and demonstrate the ability to interpret, analyze, and logically deduce answers, reflecting the evolving nature of the exam toward testing civil service aptitude more effectively.

UPSC 2025 Prelims: Overall Review
