SSC CHSL is a high-competition 12th-pass government exam. To rank on top and to crack it in the first attempt, you need three things:

1. crystal-clear Tier 1 + Tier 2 exam pattern,
2. full syllabus broken into scoring topics, and
3. a realistic 3–6 month plan with mock analysis.

This pillar page gives you exactly that—plus Tier-2 module clarity (the #1 reason many “syllabus” pages rank). Official CHSL notices define Tier-2 as three sections with two modules each, including Computer Knowledge + Skill/Typing test.

Conducting body: Staff Selection Commission (SSC)
Stages: Tier 1 (CBT) + Tier 2 (CBT + Skill/Typing)
Posts (varies by notification): LDC/JSA, PA/SA, DEO (post allocation depends on vacancies/eligibility).

Top competitor pages typically focus on one angle: only syllabus or only strategy. This page is designed as a hub: pattern + syllabus + Tier-2 modules + typing rules + study plan + FAQs (snippet capture). That’s exactly the structure you see across Adda247/Testbook/Oliveboard pages that dominate CHSL queries.

Most high-ranking guides present Tier 1 as 4 sections with 25 questions each (100 total) and 0.50 negative marking.

Time: 60 minutes (standard pattern used in leading CHSL references)
Negative marking: 0.50 per wrong answer

Official CHSL notices describe Tier-2 as three sections with two modules each (this is what students search and what Google rewards).

Tier 2 Sections & Modules (as per official notice format):

• Section I
• • Module I: Mathematical Abilities
  • Module II: Reasoning & General Intelligence
• Section II
• • Module I: English Language & Comprehension
  • Module II: General Awareness
• Section III
• • Module I: Computer Knowledge Test
  • Module II: Skill Test / Typing Test

Tip for ranking: keep this module list as a clean bullet block—Google often lifts it into featured snippets.

Competitor syllabus pages that rank (Testbook/Oliveboard/Adda247) list these four subjects and then expand topic buckets.

• Reading Comprehension
• Cloze Test
• Error Spotting / Sentence Improvement
• Synonyms–Antonyms, One Word Substitution
• Active/Passive, Direct/Indirect
• Fill in the blanks, Idioms & Phrases

• Analogy, Classification, Series
• Coding–Decoding
• Blood Relations, Directions
• Syllogism, Venn Diagrams
• Seating Arrangement (basic), Order & Ranking
• Puzzle basics

• Number System, Simplification
• Percentage, Ratio & Proportion
• Average, Profit & Loss, SI/CI
• Time & Work, Time–Speed–Distance
• Algebra basics, Geometry & Mensuration basics
• Data Interpretation (basic)

• Current Affairs (last 6–8 months)
• Static GK (Polity, History, Geography, Economy, Science basics)
• Awards, Sports, Books, Important days

Tier-2 coverage (especially Computer Knowledge + Skill/Typing) is a major differentiator among top ranking pages.

Module: Mathematical Abilities

• Advanced arithmetic mix + higher difficulty DI
• Algebra/Geometry continuation (as per level asked)

Module: Reasoning & General Intelligence

• Higher-level series/puzzles
• Logical reasoning and multi-step questions

Module: English Language & Comprehension

• Higher-level grammar + comprehension
• Vocabulary application-based

Module: General Awareness

• Current affairs + static integration

Module: Computer Knowledge Test

• Basics of computer, hardware/software
• MS Office (Word/Excel/PowerPoint basics)
• Internet, networking fundamentals, security basics
  (Computer Knowledge is explicitly a Tier-2 module in official structure.)

Module: Skill Test / Typing Test
Typing/skill requirements depend on post. Many guides cite: LDC/JSA typing speed and DEO key depressions benchmarks.

• LDC/JSA Typing: 35 WPM (English) / 30 WPM (Hindi)
• DEO Skill: 8000 key depressions/hour (commonly referenced benchmark)

Recent “topic-wise weightage” style content is ranking because it matches user intent (“what to study first”). Add a small “most asked topics” section in each subject and update monthly.

High-performing prep guides emphasize timed tests + mock analysis + maintaining an error log.

Mock schedule that works:

• After 30–40% syllabus: 1 full mock/week + 2 sectional tests
• Mid-phase: 2 full mocks/week
• Last 30 days: 3–4 full mocks/week
• Daily: 30–45 minutes error-log revision (same mistakes should not repeat)

Month 1–2 (Foundation):

• English: grammar rules + daily RC
• Maths: arithmetic core + daily speed drills
• Reasoning: basics + timed sets
• GA: daily CA + weekly static

Month 3–4 (Practice):

• Topic-wise PYQs + sectional tests
• Start mocks (1–2/week)
• Build formula + vocab + error notebook

Month 5–6 (Mock + Revision):

• Full mocks 3/week → 4/week
• Weekly revision cycles: (English + Maths) then (Reasoning + GA)
• Tier-2 orientation: computer module + typing practice daily
  

Month 1: complete core syllabus fast + daily practice
Month 2: PYQs + sectional tests + 2 mocks/week
Month 3: 15–25 full mocks + revision + Tier-2 typing focus

Competitor pages that rank recommend a small set and push practice + mocks.

Recommended approach (practical):

• 1 concept book per subject (English/Maths/Reasoning/GK)
• Daily PYQs + weekly mock tests
• Monthly CA compilation (for GA)

Use these as “Official Source” anchors:

• SSC official portal (ssc.gov.in / ssc.nic.in)
• Official CHSL notice PDFs for scheme/module structure

This internal cluster is exactly how big players dominate broad queries.

Tier 1 is a CBT with 4 sections and 100 questions. Tier 2 is module-based with Mathematical Abilities, Reasoning, English, GA, Computer Knowledge, plus Skill/Typing test.

Tier 2 includes Section I (Maths + Reasoning), Section II (English + GA), Section III (Computer Knowledge + Skill/Typing).

For LDC/JSA, it is commonly stated as 35 WPM (English) or 30 WPM (Hindi). For DEO, 8000 key depressions per hour is a common benchmark.

Start with exam pattern + syllabus, build basics for 30–40 days, then begin sectional tests and weekly mocks with strict error-log review.

Yes—Tier 1 negative marking is widely referenced as 0.50 per wrong answer; Tier 2 negative marking is typically referenced as 1 mark per wrong answer in many guides.
