High-probability questions and topics for your next exam
How to prepare for TNPSC Group 1
- Study the Tamil Nadu SCERT Samacheer Kalvi textbooks (Classes 6 to 12) cover-to-cover—nearly 75% to 80% of TNPSC Prelims questions are framed directly from or inspired by Samacheer Kalvi history, polity, geography, economy, and Thirukkural chapters.
- Prioritize Unit-8 (Tamil Nadu History, Culture, Thirukkural & Dravidian Movement) and Unit-9 (Development Administration in Tamil Nadu), which together contribute ~65 to 70 out of the 175 GS questions in Prelims and dominate Mains GS II and III.
- Do not neglect Quantitative Aptitude: it carries 25 questions (37.5 marks) in Prelims AND a full Unit (Unit III of Mains GS Paper I, carrying ~50 marks of descriptive step-by-step math problems) in the Main Examination!
- Because there is NO negative marking in TNPSC Group 1 Prelims, never leave any of the 200 OMR bubbles blank.
- If you completed your entire schooling (Class 1 to Class 12) and Bachelor's degree in Tamil medium, obtain your PSTM (Persons Studied in Tamil Medium) certificates from every institution before applying to claim the 20% horizontal PSTM reservation.
- Read the official TNPSC Group 1 notification carefully for the exact pattern, eligibility and selection stages.
