What is inside
Where the syllabus sits
CHSL asks the same four subject areas in both tiers, but Tier-II goes deeper and adds a computer paper and a skill or typing round. Reading the topics tier by tier prevents you from over-studying one level and neglecting the other.
Tier-I topics
English Language: error spotting, fill in the blanks, synonyms and antonyms, spellings, idioms, one-word substitution, sentence improvement, active and passive voice, direct and indirect speech, sentence rearrangement, cloze and comprehension passages.
General Intelligence: verbal and non-verbal reasoning covering analogies, classification, series, coding and decoding, symbolic operations, Venn diagrams, paper folding and cutting, embedded figures, word building and critical thinking.
Quantitative Aptitude: number systems, percentages, ratio, averages, interest, profit and loss, mixtures, time and work, school algebra, geometry of triangles and circles, mensuration, trigonometry and statistical charts.
General Awareness: current events, everyday science, India and its neighbours in history and culture, geography, the economy, policy and scientific research.
What changes in Tier-II
| Section | Added or deepened |
|---|---|
| Mathematical Abilities | Statistics and probability: mean, median, mode, standard deviation and simple probability |
| Reasoning | Same figural and verbal families as Tier-I |
| English and Comprehension | Two or more passages, one story-like and one on a current affairs report |
| General Awareness | Same themes as Tier-I |
Computer Knowledge and skill rounds
- Computer basics: the CPU, input and output devices, memory, backup devices and ports.
- Software: Windows, MS Word, Excel and PowerPoint.
- Internet and e-mail: browsing, downloading, e-banking and managing a mailbox.
- Networking and security: devices, protocols and threats such as viruses, worms, Trojans and hacking.
- Skill test for data entry posts and a typing test for LDC and JSA, both qualifying only.
Using the list for a study plan
Mark every topic as strong, shaky or untouched, then give shaky arithmetic and grammar topics the first weeks, since they appear in both tiers. Reasoning figure types respond well to daily short drills. General Awareness needs a steady revision habit rather than a cram. The computer section is small and qualifying, so a week of focused reading is usually enough.
About the attached PDFs
Eight official documents are listed: the 2026 notice that carries the syllabus, its Hindi version, the Tier-I schedule notice, the normalization procedure, the 2024 and 2025 result write-ups, and the earlier notices. Use the 2026 notice as the final word on the topic list.
Printed practice
Topic lists are best turned into practice, and printed SSC question books from Competer help you solve each topic on paper.
