TNPSC Group 3 Mock Tests, Syllabus & Complete Exam Guide

Both are recruited through the same objective written examination, but they differ at the final stage. Group III posts (such as Station Fire Officer and Junior Inspector of Co-operative Societies) are 'interview posts' — selection adds a 40-mark oral test. Group IIIA posts (such as Store Keeper) are 'non-interview posts', decided on the written exam alone.

Group 3 is a single objective written examination of 200 questions worth 300 marks (1.5 marks each), completed in 3 hours with no negative marking. It combines General Studies with an Aptitude & Mental Ability section and a General Tamil / General English section. Unlike Group 1 and Group 2, there is no separate Preliminary and Main stage.

For the Station Fire Officer post in the Fire & Rescue Services, yes — candidates must meet prescribed physical measurements and pass a physical efficiency test in addition to the written examination. Other Group 3 posts, such as the Co-operative Society inspectors and Store Keepers, do not require a physical test.

Group III interview posts include Station Fire Officer, Junior Inspector of Co-operative Societies and Assistant Supervisor of Industrial Co-operative Societies. Group IIIA non-interview posts include Store Keeper in departments such as Employment & Training and Industries & Commerce, and Junior Co-operative Auditor. The specific post depends on your merit and preferences.

A Bachelor's degree in any discipline is the basic requirement, along with being within the age band (generally 18–32 years, with relaxations for reserved categories) and having adequate knowledge of Tamil. The Station Fire Officer post additionally requires the prescribed physical standards.

Since a single written paper decides selection, take full-length bilingual mocks in your chosen language to rehearse attempting all 200 questions in 3 hours across General Studies, Aptitude and the language section. Use subject and topic tests to build depth — especially in Co-operation, Tamil Nadu administration and the language paper — and review each mock to close weak areas.
