SSC CHSL Syllabus 2026

SSC CHSL syllabus 2026

The SSC CHSL 2026 syllabus covers four core subjects in Tier 1 (Reasoning, Quantitative Aptitude, English and General Awareness) and the same subjects at greater depth in Tier 2, along with Computer Knowledge and a skill / typing test. Since only Tier 2 marks decide the merit list, you need a topic-level grip on every area, not just a quick overview.

Stage	Subjects
Tier 1	General Intelligence & Reasoning, Quantitative Aptitude, English Language, General Awareness
Tier 2	Mathematical Abilities, Reasoning & General Intelligence, English Language & Comprehension, General Awareness, Computer Knowledge (qualifying), Skill / Typing Test (qualifying)

The marks and timing for each section are on the SSC CHSL exam pattern page.
