Frequently asked questions
What is the SSC CHSL syllabus?
It runs to 4 sections: General Intelligence, General Awareness, Quantitative Aptitude and English Language. 39 named topics are listed on this page beneath them, each taken from the official syllabus rather than inferred from past papers.
How do I practise the whole SSC CHSL syllabus?
Sit a full mock first, before working through the topic list. A syllabus tells you what can be asked; it does not tell you which parts of it are costing you marks, and most candidates find that is not where they expected. There are 16 free tests for SSC CHSL here, and the sectional ones let you rebuild a single section once the full paper has shown you which one to rebuild.
Is this SSC CHSL syllabus current?
It is taken from the official SSC CHSL 2025 notice, cited and linked at the foot of this page, rather than from another preparation site, so you can check it against the source yourself. Syllabuses do change between cycles, usually through a corrigendum to the notification rather than a fresh document, so confirm against the current notice before planning a whole revision cycle around any topic list, including this one.
