TN Police SI cheat sheet

The Tamil Language Eligibility Test (Tamil Eligibility Test / Part A style paper) is a qualifying paper: marks are not added to the main written total, but a pass is mandatory; failing it disqualifies the candidate regardless of main exam rank.

Standard question load is 100 objective questions with 100 marks; qualifying mark is 40 (40%) for most categories, with relaxations announced in the notification - always verify the current notification figure.

No negative marking is prescribed for the language eligibility paper; the main written examination may prescribe negative marking for wrong answers, so confirm per notification.

Syllabus components: Tamil grammar (ilakkanam), Tamil literature (ilakkiyam), translation (English to Tamil and Tamil to English), and comprehension of a given Tamil passage.

Grammar topics typically tested: ezhuthu (letters/phonology), sol (words/morphology), porul (meaning/semantics), yappu (prosody/versification), ani (figures of speech), and Tamil orthography rules (e.g., 'na' vs 'na' distinctions, pulli usage).

Literature topics typically tested: Sangam literature (Ettuthogai, Pathupattu), twin epics (Silappathikaram, Manimekalai), devotional literature (Thevaram, Nalayira Divya Prabandham), and modern Tamil prose/poetry figures.

Translation questions test fidelity plus natural Tamil style; literal word-for-word rendering that violates Tamil word order (subject-object-verb) is treated as wrong.

Passing this paper is a threshold condition, not a merit component: a candidate scoring 90 here gains no rank advantage, while a candidate scoring 39 is eliminated.

The main written examination is descriptive/objective as prescribed per paper and typically carries General Knowledge (with Tamil Nadu focus), General English, Arithmetic/Reasoning, and Tamil eligibility components; the exact paper structure is fixed by the current notification.

General Knowledge weightage leans on Tamil Nadu: state history (Sangam age, Chola/Chera/Pandya, Nayak and Maratha periods), Tamil Nadu geography, state schemes, and current state affairs.

Indian polity questions target the Constitution: fundamental rights (Part III), directive principles (Part IV), fundamental duties (Article 51A), and the functioning of the Tamil Nadu Legislative Assembly and Secretariat.

Arithmetic covers number system, percentages, ratio and proportion, average, time-work, time-distance, simple/compound interest, and mensuration - speed with shortcuts matters more than depth.

Reasoning covers series, coding-decoding, blood relations, direction sense, syllogism, seating arrangement, and non-verbal figures; these are high-scoring and should be attempted first.

General English for the main exam tests grammar (tense, voice, articles, prepositions), vocabulary (synonyms, antonyms, idioms), and comprehension - plus translation into Tamil where prescribed.

Negative marking, if any, applies to objective sections only; descriptive answers are graded on content accuracy, structure, and language quality, so headings and legible presentation raise scores.

Physical efficiency (endurance run, long jump, high jump, shot put) and a medical test follow the written stage for Sub-Inspector recruitment; written merit alone does not confer selection.

Tamil Nadu state symbols and facts: capital Chennai, state animal Nilgiri tahr, state bird emerald dove, state tree palmyra palm, state flower gloriosa lily - these recur in objective GK.

Constitutional articles frequently asked: Article 14 (equality), 19 (freedoms), 21 (life and personal liberty), 32 (writs), 44 (uniform civil code), 356 (President's rule), 370 (special status, abrogated 2019).

Tamil Nadu administrative structure: 38 districts, headed by District Collector; police districts are separate from revenue districts and headed by Superintendents of Police.

Key national institutions: RBI (1935, nationalised 1949), SEBI (1992), NITI Aayog (2015, replacing Planning Commission), and ISRO headquarters at Bengaluru with launch centres at Sriharikota.

Tamil Nadu economy anchors: automobile and auto-component hub around Chennai, textiles in Coimbatore/Tiruppur, leather in Vellore/Ambur, and IT corridor along Old Mahabalipuram Road.

Police-relevant law basics: Bharatiya Nyaya Sanhita replaced the IPC, Bharatiya Nagarik Suraksha Sanhita replaced the CrPC, and Bharatiya Sakshya Adhiniyam replaced the Evidence Act, effective 1 July 2024.

Arithmetic formula anchors: speed = distance/time; work rate sums for combined workers; compound interest A = P(1 + r/100)^n; average = sum/count; percentage change = (new − old)/old × 100.

Reasoning rule anchors: in syllogism, a conclusion fails if a counter-example Venn diagram exists; in blood relations, draw the tree rather than tracking relations verbally.
