Important topics

Topics worth extra focus, based on real exam history, not a guess.

• Women, Urbanisation and Social Empowerment (within Indian Society)(GS I: Heritage, History and Geography)

  Legacy IAS Academy's mapping of 82 GS1 Mains questions across 2013–2025 found Women and Urbanisation topics have appeared "almost every single year without exception since 2013", the strongest recurrence finding across this whole research effort.

• Gandhi and Freedom-Struggle Personalities(GS I: Heritage, History and Geography)

  Legacy IAS Academy's 2013–2025 mapping of Modern Indian History questions found Gandhi-related questions the single highest-frequency named figure (8+ appearances) within that theme.

• Local Bodies (73rd/74th Constitutional Amendments)(GS II: Governance and International Relations)

  Legacy IAS Academy's mapping of 118 GS2 Polity & Constitution questions (2013–2025) found this the single most recurring sub-theme, asked essentially every year from 2013 to 2024 (10 of the 118 questions).

• Judiciary (basic structure doctrine, judicial review, collegium vs NJAC)(GS II: Governance and International Relations)

  Same Legacy IAS mapping found 11 Judiciary questions across 2013–2025, with the pattern escalating in the 2025 paper (two 15-mark judiciary questions).

• Cropping Pattern, Irrigation and Water Management(GS III: Economy, Technology and Security)

  Legacy IAS Academy's mapping of 128 GS3 Economy/Agriculture/Infrastructure questions (2013–2025) found this the single most-asked sub-theme across all 13 years, at 18 of 128 questions.

• Border Management and Cyber Security(GS III: Economy, Technology and Security)

  Legacy IAS Academy's mapping of 59 GS3 Internal Security questions (2013–2025, stable at 4–5/year every single year) found these two sub-themes together account for nearly half of all Internal Security questions (Border Management 16, Cyber Security 14, of 59 total).

• Moral Thinkers and Philosophers (Gandhi, Vivekananda, Kant and others)(GS IV: Ethics, Integrity and Aptitude)

  Legacy IAS Academy's mapping of ~155 GS4 Ethics questions (2013–2025) found this by far the largest theme (35+ questions); Vision IAS independently corroborates it as the top-frequency theme, with named thinkers appearing 3–4 times per year, 2020–2024. Individually, Gandhi appears 7 times and Vivekananda 5.

• Integrity, Impartiality and Probity in Governance(GS IV: Ethics, Integrity and Aptitude)

  Same Legacy IAS mapping found Foundational Values (15 questions) plus Probity in Governance (11 questions) together account for 26 of ~155 GS4 questions (2013–2025), recurring almost every year.
