Combined Graduate Level Examination: Quantitative Aptitude, Reasoning, English and Awareness
Scope of the exam
The CGL examination is the broadest graduate-level SSC paper, with tiers covering quantitative aptitude, general intelligence and reasoning, English comprehension, general awareness, and a descriptive component in some tiers. Quantitative aptitude extends to algebra, geometry, trigonometry, mensuration, and data interpretation. Reasoning includes series, coding, syllogism, puzzles and non-verbal reasoning. English tests grammar, vocabulary, idioms, sentence improvement and comprehension. General awareness covers history, polity, geography, economics, science and current affairs.
Traps to watch
In quantitative aptitude, geometry questions often require knowing the correct theorem rather than computing; misapplying the angle-sum or cyclic quadrilateral property wastes time. In trigonometry, standard values and identities must be recalled instantly. In English, sentence-improvement items hide subtle tense or preposition errors. In general awareness, candidates confuse similar-sounding schemes and dates. Data interpretation is often left for last and then rushed, causing silly errors.
Rule of thumb and worked example
Rule: in geometry, draw the figure and mark known angles before calculating. Example: in a cyclic quadrilateral, opposite angles sum to 180°. If one angle is 70°, the opposite is 110°. Recognising the property takes seconds, whereas deriving it takes minutes.
Preparation approach
Revise formulae with derivations for geometry and trigonometry, practise DI sets daily, and maintain a current-affairs log. Take full mocks to fix section order and time allocation.
