TNPSC Group 1 Prelims – Topic Weight and Trend Analysis from PYQs

TNPSC Group 1 has a unique syllabus with Tamil Nadu-specific history, geography, and governance questions. Here is the PYQ frequency map and what it means for your prep.

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.

In Polity, TNPSC leans heavily on local governance — Panchayati Raj institutions, Tamil Nadu-specific commissions, and state legislative procedures. Constitutional Amendments related to local self-government (73rd and 74th) appear at noticeably higher frequency compared to other state PSCs.
pscprep.ai tracks subtopic-level frequency for every topic in TNPSC — not just which subjects are heavy, but which specific subtopics have appeared most, which are trending up, and which you can safely deprioritise. Sign in free (no credit card) to see the full subtopic breakdown for your exam.

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.
