This page collects what candidates most often look for about the TNUSRB Sub Inspector examination. TNUSRB Sub Inspector recruits for Sub Inspector posts in the Tamil Nadu police, including a physical and endurance stage. Figures and dates on this page describe how the examination has been conducted in recent cycles; always confirm the current position against the official notification before you rely on it for a decision.

Preparing for TNUSRB Sub Inspector

Begin by reading the official notification end to end, including the parts about eligibility and document requirements. A surprising number of candidates lose a full cycle to a qualification or age detail they never checked, and no amount of preparation recovers that.

Build your preparation around the prescribed syllabus and the standard state board textbooks rather than around a stack of competing guidebooks. One source read three times is worth more than three sources read once, because the examination rewards recall of settled material far more often than it rewards breadth.

A workable study pattern

Split your available hours into three roughly equal parts: new material, revision of material you covered in previous weeks, and timed practice. Candidates who skip the second part can usually answer anything they studied last week and very little of what they studied two months ago, which is the single most common reason a well-prepared candidate underperforms.

Keep a one-page running note for each subject with the facts you keep forgetting. Revise only that page in the final fortnight. Trying to re-read entire books in the last two weeks produces anxiety rather than marks.

The Tamil Nadu Uniformed Services Recruitment Board (TNUSRB) recruits Sub-Inspectors of Police (SI) for the Taluk, Armed Reserve and Tamil Nadu Special Police wings. Selection combines a written examination with Physical Measurement and Efficiency Tests. This guide covers the eligibility, pattern, syllabus and a realistic study plan for TNUSRB SI.

Eligibility (overview)

• Qualification: a bachelor’s degree from a recognised university.
• Age: as specified by TNUSRB, with relaxation for reserved categories.
• Physical standards: minimum height, chest and running/jumping norms (differ by gender/category).

Selection process & exam pattern

1. Written examination — objective paper testing General Knowledge, Psychology/aptitude and a Tamil eligibility / communication component (100 marks).
2. Physical Measurement Test (PMT) — height, chest verification.
3. Physical Efficiency Test (PET) — running, jumping and other events with marks.
4. Certificate verification and final merit based on written + PET.

Syllabus focus areas

• General Knowledge & general studies (national and Tamil Nadu)
• General Science, History, Geography, Polity & Economy basics

• Psychology and situational judgement (for the SI paper)

A study plan that works

1. Build GK/GS from Samacheer Kalvi textbooks, then layer study materials.
2. Practise aptitude and reasoning daily for speed.
3. Train physically in parallel — PET is decisive; start running practice early.
4. Take full-length mock tests and solve previous year SI papers weekly.
