Constable (GD) CAPFs, SSF, Rifleman (GD) and Sepoy: Objective Test Essentials
What the exam emphasises
The GD constable examination is a computer-based objective test with four parts: general intelligence and reasoning, general knowledge and general awareness, elementary mathematics, and English or Hindi. The difficulty is moderate but the breadth is wide, and speed matters because there is negative marking. Reasoning includes analogies, odd-one-out, series, coding and spatial reasoning. Mathematics stays at class-10 level: simplification, percentage, average, ratio, profit and loss, time and work, and basic mensuration. General awareness includes Indian history, geography, polity, science and current events, with a strong tilt towards defence and national institutions.
Traps to watch
Because negative marking applies, blind guessing costs marks; eliminate at least two options before answering. In mathematics, questions often ask for 'approximate value', so exact long computation wastes time. In general awareness, questions about ranks, capitals and founding years are commonly confused. In reasoning, mirror-image and paper-folding items punish careless visual assumptions.
Rule of thumb and worked example
Apply the 80-20 attempt rule: answer only where you can eliminate down to two choices, and skip pure guesses. Example: a shopkeeper marks an item 40% above cost and gives a 25% discount. Profit percentage = 140 × 0.75 = 105, so profit = 5%. Working with a base cost of 100 avoids fractions and is far quicker than algebra.
Preparation approach
Practise sectional tests with a timer, revise basic formulae and tables, and read a daily newspaper summary for current affairs. Physical fitness preparation should run in parallel with written study.
