Translation direction rule

Tamil is subject-object-verb order; English is subject-verb-object. A correct translation reorders clauses and uses Tamil case markers rather than preserving English word order literally.

Comprehension strategy

Read the Tamil passage questions first, then scan for the relevant line. Answers must be supported by the passage text, not by outside knowledge or personal opinion.

Main written exam nature

A multi-paper written stage combining objective and descriptive components, covering Tamil, General English, General Knowledge, arithmetic, and reasoning as fixed by the current notification.

Tamil Nadu state animal

The Nilgiri tahr (Nilgiritragus hylocrius), a mountain ungulate endemic to the Western Ghats. State symbols such as this recur in objective general knowledge questions.

Article 32 of the Constitution

The right to constitutional remedies, allowing a person to move the Supreme Court directly by writ for enforcement of fundamental rights. Dr. Ambedkar called it the heart of the Constitution.

Percentage change formula

Percentage change equals (new value minus old value) divided by old value, multiplied by 100. A negative result indicates a decrease; the denominator is always the original value.

Compound interest formula

Amount A equals P multiplied by (1 + r/100) raised to n, where P is principal, r the annual rate percent, and n the number of years. Interest is A minus P.

Combined work rule

If one worker finishes a job in x days and another in y days, together they finish it in xy/(x + y) days, because their one-day rates 1/x and 1/y add.

Speed-distance-time

Speed equals distance divided by time. To convert km/h to m/s multiply by 5/18; to convert m/s to km/h multiply by 18/5. Used in train and relative-speed problems.

Syllogism counter-example

A conclusion is valid only if it holds in every possible Venn diagram of the premises. One diagram in which the conclusion fails makes it invalid.

Blood relations method

Draw a family tree using symbols for gender and generation, then read the question from the tree. This avoids errors from chained verbal descriptions in multi-step relations.

Physical efficiency test

A post-written qualifying stage for Sub-Inspector recruitment covering an endurance run plus long jump, high jump, and shot put, followed by a medical examination.

Negative marking caution

Where prescribed, wrong objective answers deduct marks while unattempted questions do not. Blind guessing is therefore costly; eliminate options before attempting a doubtful question.
