SSC CHSL Syllabus 2026 with Detailed Topic-Wise Breakdown

The SSC CHSL 2026 syllabus determines exactly what you need to study for Lower Division Clerk (LDC)/Junior Secretariat Assistant (JSA) and Data Entry Operator (DEO) posts. Knowing the full topic-wise breakdown — not just the section names — is what separates focused preparation from guesswork. Here's the complete SSC CHSL syllabus for both Tier 1 and Tier 2, explained simply.

SSC CHSL Exam Structure at a Glance

Tier 1 has 100 questions across four sections, each locked at a strict 15-minute sectional timer — meaning you cannot use extra time saved in one section for another. Visit the SSC CHSL exam page for eligibility, age limit and post details alongside this syllabus.

SSC CHSL Tier 2 Syllabus — What Changes

Tier 2 tests the same four broad areas but at a slightly higher difficulty level, and includes an essay/letter-writing descriptive module for certain posts, along with a mandatory skill test:

• For DEO posts: A Data Entry Speed Test, typically requiring a set number of key depressions per hour
• For LDC/JSA posts: A Typing Test in English or Hindi at the prescribed speed

These skill tests are qualifying in nature but mandatory — clearing the written stage without meeting the typing/DEO speed requirement means you won't be selected, so start practicing typing speed early rather than only after Tier 1 results.

Section-Wise Preparation Tips

General Intelligence & Reasoning

Focus on daily practice of pattern-based questions rather than memorisation — this section rewards consistent problem-solving practice over rote learning.

General Awareness

Cover static GK first since it stays relevant for months, then layer in current affairs from our Current Affairs section during the final weeks before your exam.

Quantitative Aptitude

Build arithmetic speed first (it appears most frequently), then move to algebra, geometry and trigonometry. Practice short calculation tricks to save time under the 15-minute sectional limit.

English Language

Grammar rules and vocabulary lists are faster to master than long comprehension passages — prioritise them if you're short on time, but don't skip comprehension practice entirely.

How to Use This Syllabus Effectively

1. Print or save this topic list and tick off each topic as you complete it.
2. After finishing a topic, immediately solve related questions from PYQs and our practice papers.
3. Take free mock tests under the real 15-minute sectional-timer format once your syllabus coverage crosses 60–70%.
4. Revisit weak topics identified from mock analysis rather than re-reading the entire syllabus repeatedly.

Frequently Asked Questions (FAQs)

1. What is the SSC CHSL 2026 Tier 1 syllabus?

It covers General Intelligence & Reasoning, General Awareness, Quantitative Aptitude and English Language, with 25 questions each, totalling 100 questions and 200 marks.

2. Does SSC CHSL Tier 1 have a sectional timer?

Yes, each of the four sections has a fixed 15-minute timer, and time cannot be transferred between sections.

3. Is SSC CHSL Tier 1 used for final selection?

No, Tier 1 is qualifying only. Final merit is decided by Tier 2 performance.

4. What additional test is required for DEO posts?

A Data Entry Speed Test measuring key depressions per hour, conducted as part of the skill test stage.

5. What additional test is required for LDC/JSA posts?

A Typing Test in English or Hindi at the prescribed speed, conducted after the written exam stages.

6. Which topics carry the most weightage in Quantitative Aptitude?

Arithmetic topics like percentage, ratio, profit-loss and time-work appear most frequently, followed by algebra, geometry and trigonometry.

7. Is the SSC CHSL syllabus the same as SSC CGL?

The broad sections are similar, but SSC CHSL is generally considered slightly less advanced, especially in Quantitative Aptitude and English difficulty level.

8. How should I prioritise topics with limited time?

Focus on high-frequency arithmetic, common reasoning patterns, grammar rules and static GK first, since these yield the fastest score improvement.

9. Should I start typing practice before or after Tier 1?

Start typing practice early, alongside your written preparation, since typing speed takes weeks to build and cannot be rushed after Tier 1 results.

10. How many questions are asked from General Awareness in Tier 1?

25 questions, covering a mix of static GK and current affairs.

11. Is there negative marking in SSC CHSL?

Yes, Tier 1 typically carries negative marking for wrong answers — always confirm the exact deduction from the latest official notification.

12. Can I skip English preparation if I'm weak in it?

No, English carries equal weightage to other sections — focus on grammar rules and vocabulary first for quicker improvement.

13. Where can I find previous year papers for SSC CHSL?

All previous year papers are available on our PYQs page, organised for topic-wise practice.

14. How do I practice under the real exam time format?

Use free mock tests that replicate the 15-minute sectional-timer format instead of untimed practice sets.

15. Does the syllabus change every year?

The core syllabus remains largely stable, but always cross-check the latest official notification for any changes before you start preparing.

16. What is the best way to revise this syllabus before the exam?

Use a topic checklist, revisit only your weak areas identified through mock analysis, and avoid re-reading the entire syllabus passively in the final days.
