What the PYQs Actually Show
TNPSC Group 1 Prelims has 200 questions covering General Studies, Aptitude, and Mental Ability. The GS portion is heavily tilted towards Tamil Nadu-specific content — state history, the Dravidian movement, Tamil literature, and TN governance carry significant weight alongside standard UPSC-style topics.
Topic Weight: Where the Questions Actually Come From
History (Indian + Tamil Nadu) is the largest block at 20–25% of the paper, with TN history (Chola, Pandya, Pallava dynasties, Dravidian movement) as a major component. Polity and Governance follows at ~15–18%. Geography ~12%, Economics ~10%, Science ~12%, and Current Affairs ~10–12%. Aptitude and Mental Ability together contribute ~15%.
Subtopic Spotlight: A Preview
Within TN History, the Chola dynasty (administration, temple architecture, naval power) is the single most-tested subtopic — appearing in nearly every paper. The Dravidian movement (Periyar, social reform, Self-Respect movement) is another reliable cluster at ~20% of the history block. Sangam literature and its historical significance surfaces consistently.
Year-over-Year Trend Shifts
Tamil Nadu government schemes (Kalaignar insurance, Amma canteens, Naan Mudhalvan) have become a prominent testing area. Science questions now include more questions on Indian space missions and indigenous technology. Environment and ecology questions have grown, with Western Ghats biodiversity, Nilgiri Biosphere Reserve, and Gulf of Mannar appearing regularly.
How to Use This in Your Prep
TN History is non-negotiable — build a strong foundation on Chola, Pandya, Pallava, and the Dravidian movement before anything else. For Polity, study local self-government in detail alongside the Constitution. Do not neglect Aptitude and Mental Ability — it is a pure scoring section if you practice regularly.
