SSC CHSL Syllabus

English Language

Spotting errors, fill in the blanks, synonyms and antonyms, spelling detection, idioms and phrases, one-word substitution, sentence improvement, active and passive voice, direct and indirect narration, para jumbles, cloze passage and comprehension passage. This section carries the highest scoring potential for a prepared candidate because it is almost entirely learnable in advance.

General Intelligence

Semantic and figural analogy, classification, series, coding-decoding, problem solving, word building, numerical operations, symbolic operations, space orientation, Venn diagrams, figural pattern folding and completion, embedded figures, and critical thinking. Both verbal and non-verbal reasoning appear.

Quantitative Aptitude

Number systems, fundamental arithmetical operations, percentage, ratio and proportion, square roots, averages, interest, profit and loss, discount, partnership, mixture and alligation, time and distance, time and work. Algebra covers basic identities and linear equations; geometry covers triangles, circles and their basic properties; mensuration covers standard plane and solid figures; trigonometry stays at ratios, identities and simple heights and distances; and data interpretation appears through bar graphs, pie charts, histograms and frequency polygons.

General Awareness

India and its neighbouring countries — history, culture, geography, economic scene, general polity and the Constitution, scientific research, and current events. Questions test everyday general knowledge rather than specialist depth in any one area.

Computer Knowledge (Tier 2)

Computer fundamentals, organisation, input and output devices, memory, software and operating system basics, MS Word, Excel and PowerPoint essentials, internet and email, and basic cyber security awareness.

One practical note on scope. CHSL quantitative aptitude stays close to arithmetic and school-level algebra and geometry; the advanced mensuration and trigonometry that dominate CGL Tier 2 do not carry the same weight here. If your time is limited, arithmetic fluency and error-free English will move your score further than advanced mathematics will.

Within general awareness, the CHSL syllabus wording — history, culture, geography, economic scene, general polity and scientific research — is broad enough to be unhelpful as a study plan. Past papers narrow it considerably: Indian polity and the freedom movement recur, general science stays at school level, and static items such as important days, national parks, classical dances and major awards appear far more often than the phrase about current events would suggest.
