TNPSC Group 1 Exam Pattern
Prelims
The Prelims exam carries 300 marks over 3 hours, split into two parts: Part A (General Studies, 175 questions, degree standard) and Part B (Aptitude & Mental Ability, 25 questions, SSLC standard). Unlike UPSC Prelims, there is no negative marking in TNPSC Group 1 Prelims.
Mains
The Mains exam carries 750 marks across four papers, each of 3 hours: Paper I (Tamil, 100 marks, qualifying only), and Papers II-IV (General Studies I-III, 250 marks each, counted for merit). The Interview carries 100 marks. The final merit list is prepared out of 850 marks — the total of the Mains General Studies papers (750) and the Interview (100); Tamil is qualifying and is not added to the merit score.

How to Prepare for TNPSC Group 1
- Start with Tamil Nadu state board textbooks for History, Geography, and Polity — these form the backbone of the Tamil Nadu-specific questions in both Prelims and Mains.
- Give dedicated time to the Tamil Nadu Focus and Tamil Society units — these are unique to TNPSC and often decide the difference between a good and an average score.
- Build a daily current affairs habit covering both national and Tamil Nadu-specific developments — see our UPSC Current Affairs guide for a complete source-and-revision system that works just as well for TNPSC.
- Practice structured Mains answer writing for the General Studies papers — our UPSC Mains Exam guide covers answer-writing techniques that transfer directly to TNPSC Mains.
- Solve previous TNPSC Group 1 papers to understand the exact difficulty level and question style the Commission favors.
Common Mistakes to Avoid
- Neglecting the Tamil qualifying paper — failing to clear it disqualifies you regardless of your General Studies score.
- Treating Prelims like UPSC Prelims and skipping guesses out of fear of negative marking — TNPSC Group 1 Prelims has no negative marking.
- Under-preparing Tamil Nadu-specific content, which carries significant weight across both Prelims and Mains.
- Ignoring notification updates — as seen this cycle, exam dates can shift (the 2026 Prelims was postponed from 6 September to 27 September).
