TNUSRB SI Syllabus 2026 – Overview

The first step to cracking the TNUSRB SI Exam 2026 is mastering the syllabus and exam pattern. The TNUSRB SI syllabus 2026 for the written stage is split into two papers — a qualifying Tamil Language Eligibility Test and a merit-deciding Main Written Examination covering General Knowledge and a Psychology (Aptitude & Reasoning) test. For Open Quota (fresh) candidates, the Main Exam has 140 questions for 70 marks, with no negative marking. Below is the complete TNUSRB SI syllabus 2026 in English and Tamil with topic-wise detail.

Detail	Information
Conducting Body	Tamil Nadu Uniformed Services Recruitment Board (TNUSRB)
Post Name	Sub-Inspector of Police (Taluk, AR & TSP)
Question Type	Multiple Choice Questions (MCQs)

Mode of Exam	Offline – OMR Based (Pen and Paper)
Part I (Tamil Test) Qualifying Marks	Minimum 40 out of 100 (40% – mandatory)
Main Exam Qualifying Marks (Open)	Minimum 25 (35%)

Part I – Tamil Language Eligibility Test (100 Questions, 100 Marks)

This stage is common and compulsory for both Open and Departmental candidates and is qualifying in nature — its marks are not counted in the final merit list, but failing it disqualifies you from evaluation. Each question carries 1 mark, and the test is based on the 10th standard (SSLC) Tamil syllabus of the Tamil Nadu State Board. The TNUSRB SI syllabus in Tamil for this paper is divided into three parts.

பகுதி – அ (இலக்கணம் / Grammar)

எழுத்து இலக்கணம் – எழுத்துகளின் வகை, பிறப்பு, முதல்/சார்பெழுத்துகள், புணர்ச்சி, மயங்கொலிகள்
சொல் இலக்கணம் – பெயர்ச்சொல், வினைச்சொல், இடைச்சொல், உரிச்சொல், வேற்றுமை, ஆகுபெயர்
பொது இலக்கணம் & பொருள் இலக்கணம் – அகப்பொருள், புறப்பொருள்
யாப்பு இலக்கணம் & அணி இலக்கணம் – வெண்பா, ஆசிரியப்பா, உவமை/உருவக அணி
மொழித்திறன் – பிரித்து/சேர்த்து எழுதுதல், எதிர்ச்சொல், பிழை திருத்தம், பொருந்தாச் சொல்

பகுதி – ஆ (இலக்கியம் / Literature)

திருக்குறள், தொல்காப்பியம், கம்பராமாயணம்
எட்டுத்தொகை, பத்துப்பாட்டு, ஐம்பெருங்காப்பியங்கள், ஐஞ்சிறுகாப்பியங்கள்
பக்தி இலக்கியம், சிற்றிலக்கியம், நாட்டுப்புற இலக்கியம், புதுக்கவிதை

பகுதி – இ (தமிழ் அறிஞர்களும் தமிழ்த்தொண்டும் / Tamil Scholars & Service)

தமிழ் அறிஞர்கள், தமிழின் தொன்மை, தமிழர் பண்பாடு
தமிழ் உரைநடை, தமிழ்த்தொண்டு, சமுதாயத் தொண்டு தொடர்பான செய்திகள்

Preparation Note: Since the standard is Class 10, the Tamil Nadu State Board (Samacheer Kalvi) Tamil textbooks up to the 10th standard cover the bulk of this paper. Clearing the 40% threshold here is non-negotiable — prioritise grammar and Thirukkural-based questions.

Part II-A – General Knowledge Syllabus (80 Questions, 40 Marks)

General Knowledge is the largest scoring block in the Main Written Examination, carrying 40 of the 70 marks for Open Quota candidates. The TNUSRB SI GK syllabus 2026 spans six broad areas, with a strong emphasis on India and Tamil Nadu–specific awareness and current affairs.

Subject	Key Topics
General Science	Physics, Chemistry, Biology – inventions and discoveries, scientists and their contributions, human physiology, diseases (causes, cure, prevention), diet and nutrition, genetics, environment and ecology, acids, bases and salts, motion, light, electricity
History	Indian History from the Indus Valley Civilization to modern India; important events of World history
Geography	Regions of India, monsoon and climate, crops, towns and places, major ports, minerals, industries, power plants, forests and wildlife, national parks, population distribution
Economics	Agriculture in India, industrial and rural development, price policy, inflation, population and unemployment, imports and exports, Five-Year Planning
Indian Polity	Indian Constitution, citizenship, elections, Parliament and State legislatures, executive, judiciary, local self-government, Centre–State relations, foreign policy
GK & Current Affairs	Latest developments in science and technology, political developments, arts and culture of India and Tamil Nadu, sports, national and international awards and organizations, abbreviations, Who's Who, books and authors, India and its neighbours

Strategy Tip: Tamil Nadu–specific arts, culture, and current affairs appear regularly, so maintain a dedicated Tamil Nadu GK and daily current-affairs note alongside standard Samacheer Kalvi Science and Social Science textbooks.

Part II-B – Psychology Test: Aptitude & Mental Ability (60 Questions, 30 Marks)

The Psychology Test (Part B) carries 30 marks across 60 questions and assesses reasoning, numerical ability, and language skills. This section is highly scoring with consistent practice, and — like the rest of the paper — has no negative marking, so every question should be attempted.

Subject	What is Tested
Logical Analysis	Analysing given information logically to identify its various dimensions
Numerical Analysis	Quick numerical ability and calculation speed
Communication Skills	Effective usage of Tamil and English languages
Information Handling Ability	Drawing inferences and identifying connected facts from given information
Mental Ability	Drawing conclusions through inductive and deductive reasoning

Preparation Note: Reasoning and numerical questions follow predictable patterns. Practising directly from TNUSRB SI previous-year papers is more effective than any single guidebook for this section.

Expert Preparation Tips

TNUSRB SI Exam 2026 Preparation Tips

Clearing the TNUSRB SI Exam 2026 in the first attempt demands a smart, structured strategy rather than long unfocused hours. With the Sub-Inspector recruitment covering a Tamil Eligibility Test, a Main Written Exam, and demanding physical tests, candidates need a plan that balances General Knowledge, Aptitude, and Mental Ability with physical readiness. The expert TNUSRB SI preparation tips below are designed to help aspirants maximise their score, build exam-day confidence, and stay ahead of the competition.

1. Understand the TNUSRB SI Syllabus & Exam Pattern

Before starting, study the complete TNUSRB SI Syllabus and Exam Pattern 2026. Know the marks split — General Knowledge, Logical and Analytical Reasoning, and Psychology — and the qualifying nature of the Tamil Eligibility Test. A clear grasp of the pattern lets you prioritise high-weightage units and avoid wasting time on low-yield topics.

2. Build a Realistic Study Plan

Create a daily and weekly timetable that allocates fixed slots to each subject. Identify your strong, average, and weak areas early, and dedicate extra time to the weaker sections. Set measurable daily goals and keep one slot reserved every week for full revision.

3. Strengthen Aptitude & Mental Ability

Aptitude and reasoning carry decisive weight in the merit-scoring Main Exam. Focus on the basics first — understand the logic behind each concept rather than memorising. Practise TNUSRB SI aptitude questions daily across topics like series, coding-decoding, data interpretation, and analytical reasoning to build both speed and accuracy.

4. Take Mock Tests & Free Online Tests

Regular TNUSRB SI mock tests and free online tests simulate real exam conditions and reveal your weak spots. Attempt them in a strict time-bound setting to sharpen time management. Review every test to track improvement and refine your question-attempt strategy — always start with the questions you find easiest.

5. Solve TNUSRB SI Previous Year Question Papers

Solving TNUSRB SI previous year papers is one of the most effective ways to crack the exam. They familiarise you with the question format, difficulty level, and recurring topics, while improving accuracy and reducing silly errors. Treat each paper as a timed practice run to gauge your real-time performance.

6. Prepare for the Physical Tests (PMT & PET)

The Sub-Inspector role requires physical fitness, so begin training early. Build stamina through regular running, and practise the events tested in the Physical Measurement Test (PMT) and Physical Efficiency Test (PET). Combine fitness training with proper nutrition, adequate sleep, and a positive mindset.

7. Stay Updated with Current Affairs & Tamil Nadu GK

Read newspapers daily and maintain short notes on national, international, and Tamil Nadu–specific current affairs. Concise, self-made notes make last-minute revision faster and help retain key facts for the General Knowledge section.

Quick Last-Minute TNUSRB SI Preparation Tips

Revise from your own short notes — avoid starting any new topic.
Solve at least one full-length mock test or previous year paper daily.
Focus on accuracy first, then speed.
Keep practising aptitude and mental ability questions.
Maintain your physical training routine without overexertion.
Stay calm, sleep well, and reach the exam centre early.

How to Prepare for the TNUSRB SI Viva-Voce / Interview

For the final interview stage, research the Tamil Nadu Police department and the Sub-Inspector job profile. Be thoroughly familiar with the details in your application and resume, dress formally, maintain confident body language and eye contact, and arrive at the venue well before time.

Cut-Off Analysis & Trends

The TNUSRB SI cut-off 2026 is the minimum marks a candidate must score to qualify for the next stage of selection. TNUSRB releases the cut-off separately for each community/category and for both the Open Quota and Departmental Quota, along with the result, on the official website tnusrb.tn.gov.in. The cut-off is calculated on the final merit total of 100 marks — comprising the Main Written Examination (70 marks for Open Quota), the Physical Efficiency Test (15 marks), the Viva-Voce (10 marks), and Special Marks (5 marks). The Tamil Language Eligibility Test and the Physical Measurement and Endurance Tests are only qualifying in nature.

The TNUSRB SI cut-off marks fluctuate every year depending on the number of vacancies, the total number of applicants, the difficulty level of the question paper, and overall candidate performance. A higher applicant-to-vacancy ratio or an easier paper generally pushes the cut-off upward. Analysing previous-year cut-off trends is the most reliable way to set a realistic target score.

Category	Open Quota (out of 100)	Departmental Quota (out of 100)
General / UR (OC)	62.5	79.0
BC / OBC	61.0	77.5
MBC & DNC	60.5	77.5
SC	60.0	75.5
SC (Arunthathiyar)	53.0	72.0
ST	54.5	69.5

Indicative previous-year (2020) cut-off marks for reference only. Actual figures vary each cycle by roughly ±5 marks. The official TNUSRB SI 2026 cut-off will be published with the result on tnusrb.tn.gov.in.

Separate from the merit cut-off, candidates must also clear the minimum qualifying marks: at least 40 marks (40%) in the Tamil Language Eligibility Test, and a minimum of 25 marks (35%) in the Main Written Examination for Open Quota candidates (30 marks for Departmental candidates). Physical standards must also be met, as the physical tests are mandatory qualifying stages regardless of written score.

Maintain balanced preparation across all sections — General Knowledge and the Psychology (Aptitude & Reasoning) test — to avoid weak areas that drag down your merit score.
Solve TNUSRB SI previous-year question papers to understand cut-off trends and the realistic score needed for your category.
Since there is no negative marking, attempt every question — leaving answers blank only costs you marks.
Treat physical fitness as decisive: the PET carries 15 merit marks and can make or break selection despite a strong written score.
Aim to score well above your category's expected cut-off to create a safety margin against year-on-year fluctuations.
