General Observations on UPSC IAS Prelims 2025 (GS-I)

The UPSC Civil Services Preliminary Examination 2025 (GS-I) reflected a clear shift towards depth, integration, and conceptual clarity, reaffirming the Commission’s long-standing philosophy of testing understanding rather than rote recall.

Overall, the paper can be classified as moderately difficult, with questions across subjects ranging from easy to highly challenging. Almost every section blended core static fundamentals with strong current-affairs orientation, making the paper both relevant and demanding.

🔍 Nature & Pattern of Questions

• The option format was consciously twisted, with increased use of Roman numerals (I, II, III) instead of simple numerical options.
• Assertion–Reason type questions saw a noticeable rise, including variants involving one assertion supported by two reasons, thereby reducing blind elimination techniques.
• Several questions, though appearing to be from a single topic, required layered knowledge and cross-linking of multiple facts, testing conceptual maturity rather than memory.

📚 Subject-wise Observations

• Static subjects such as Geography, Environment, Economics, Science & Technology, Polity, and Ancient & Modern History received due and balanced weightage.
• In contrast, Art & Culture and Medieval History saw a relative dip, indicating a subtle but important pattern shift.

Polity & Governance

• UPSC focused on deep core constitutional themes, demanding precise understanding of:
  • Anti-defection law
  • Pardoning powers
  • Ordinances
• Unlike the previous year, no direct questions on political philosophy or the Preamble were asked.
• Governance questions tested institutional clarity, with focus on bodies such as:
  • Enforcement Directorate (ED)
  • Directorate of Revenue Intelligence (DRI)
  • Regulatory boards like the National Automotive Board

International Relations

• The IR section reinforced the importance of continuous newspaper engagement and mapping practice.
• Questions were largely on expected lines, with emphasis on:
  • Regional groupings (BIMSTEC, BRICS)
  • International memberships (e.g., NATO)
  • UN-declared years

History

• Ancient and Modern History dominated, while Medieval and Art & Culture receded.
• The questions leaned heavily towards standard static themes, occasionally inspired by current affairs, such as:
  • Rajendra Chola I and the Srivijaya invasion (linked to renaming of Port Blair as Sri Vijaya Puram)
  • Gandhi Peace Prize–related developments

Geography & Environment

• Geography covered both NCERT fundamentals (isotherms, International Date Line) and advanced applications (INSTC corridor, time zones).
• Environment showed a clear departure from species-centric questions, instead focusing on:
  • Contemporary issues like climate change
  • Emerging technologies such as Direct Air Capture and artificial rainfall

Economy

• The number of questions aligned with the 10-year average.
• Coverage included:
  • Fiscal policy and Union Budget
  • Agriculture
  • Digital payment systems
• Notably:
  • No direct question on National Income Accounting
  • Two calculation-based questions on government revenue and expenditure
  • Increased emphasis on financial markets (AIFs, stock market)

Science & Technology

• Questions spanned space, defence, IT, biotechnology, and frontier technologies.
• Except for two basic science questions, most were current-affairs driven.
• Interestingly, Electric Vehicles featured in two questions, indicating thematic importance.
• Overall difficulty ranged from moderate to difficult.

🧠 Key Takeaways for Aspirants

• Despite UPSC consciously limiting mechanical elimination techniques, intentional, observational, and concept-based learning remains the only sustainable strategy.
• Standard textbooks and holistic coverage continue to be indispensable.
• Current affairs must be prepared comprehensively, as even static questions increasingly draw inspiration from recent developments.
• General awareness themes such as sports achievements and international years, though limited, cannot be ignored.
