Over 25 lakh students apply for SSC CGL annually, but only 8,000-9,000 candidates receive final selection. The multi-tier exam pattern confuses most aspirants, leading to poor time management and unexpected eliminations at later stages.
This guide breaks down the complete SSC CGL exam pattern 2025 across all four tiers. You'll learn the exact structure, marking scheme, qualifying criteria, and what each tier actually tests.
Critical Warning
By understanding this pattern now, you'll avoid the mistake that costs 40% of candidates their selection: underestimating Tier 3 and Tier 4 after clearing Tier 2.
Quick Answer (30-Second Read)
- Tier 1: 60 questions (200 marks), 60 minutes, computer-based test covering General Intelligence, Quantitative Aptitude, English, and General Awareness

SSC CGL Tier 1 Exam Pattern: The Screening Stage
Tier 1 acts as your entry ticket. The Staff Selection Commission conducts this computer-based examination with 60 questions carrying 200 marks, to be completed in 60 minutes.
Subject-wise Distribution
| Subject | Questions | Marks |
|---|---|---|
| General Intelligence & Reasoning | 15 questions | 50 marks |
| General Awareness | 15 questions | 50 marks |
| Quantitative Aptitude | 15 questions | 50 marks |
| English Comprehension | 15 questions | 50 marks |
Marking Scheme: Each correct answer gives you 2 marks. Every wrong answer deducts 0.50 marks (negative marking applies). The exam uses a normalization process across different shifts to ensure fairness.
Qualifying Criteria for Tier 1
You need to score above the cutoff in each section individually. According to SSC CGL 2023 data, the Tier 1 cutoff ranged from 138-158 marks for General category depending on the post. OBC cutoffs were 5-8 marks lower, while SC/ST cutoffs were 12-18 marks lower.
Candidates are shortlisted for Tier 2 at a ratio of 1:20 of total vacancies. If SSC announces 10,000 vacancies, approximately 2,00,000 candidates move to Tier 2.
SSC CGL Tier 2 Exam Pattern: The Main Selection Battle
Tier 2 determines your final post and department. This tier expanded significantly from previous years, now consisting of three separate papers instead of two.
Paper 1: Mathematical Abilities
Compulsory for All
- Questions: 90 (300 marks)
- Duration: 2 hours
- Topics: Arithmetic, Algebra, Geometry, Trigonometry, Statistics
Paper 2: English Language
Compulsory for All
- Questions: 90 (300 marks)
- Duration: 2 hours
- Topics: Grammar, vocabulary, comprehension, writing ability
Paper 3: Statistics
Only for Specific Posts
- Questions: 100
- Duration: 2 hours
- Topics: Statistical analysis, data interpretation
Marking Scheme: Each correct answer awards 3 marks in all papers. Wrong answers carry 1-mark negative marking. The normalization formula applies here too.
Tier 2 Qualifying Marks
You must score minimum qualifying marks in each paper: 30% for General/EWS, 25% for OBC, and 20% for SC/ST categories. However, qualifying alone doesn't guarantee selection.
Aarav from Jaipur scored 165/300 in Paper 1 and 198/300 in Paper 2 (total 363/600) but couldn't secure his preferred AAO post because the cutoff reached 385 marks for General category in 2023.
Your Tier 1 + Tier 2 combined score (with 3:1 weightage ratio) determines your rank and post allocation.
SSC CGL Tier 3 Exam Pattern: The Descriptive Challenge
Tier 3 catches most candidates off-guard. This pen-and-paper descriptive test carries 100 marks with 60 minutes duration. You can write in English or Hindi (except for positions requiring English proficiency).
Question Types
- Essay writing (60-80 marks typically)
- Letter writing (formal/informal)
- Application writing
- Precis writing
The SSC evaluates content quality, grammatical accuracy, vocabulary usage, and adherence to word limits. Minimum qualifying marks: 33% (General), 30% (OBC), 25% (SC/ST/PwD).
Critical Point
Tier 3 is qualifying only—your marks don't add to final merit. But failing here eliminates you completely, regardless of your Tier 1-2 performance. In 2023, approximately 15,000 candidates cleared Tier 2 but failed Tier 3 due to poor descriptive writing skills.
Prerna from Mumbai cleared Tier 2 with 412 marks but scored only 28/100 in Tier 3, falling short of the 33-mark requirement. She lost her Tax Assistant position because she practiced only objective questions.
SSC CGL Tier 4 Exam Pattern: The Final Verification
Tier 4 varies based on your post requirements. It's qualifying in nature but mandatory for final selection.
Skill Test Components
Data Entry Speed Test (DEST)
- Required for: Tax Assistants (Central Excise & Income Tax)
- Target: 8,000 key depressions in 15 minutes (2,000 words)
- Test on computer with 15-20 passages
Computer Proficiency Test (CPT)
- Required for: Assistants in CSS, MEA, Inspector (Preventive Officer, Examiner)
- Tasks: Word processing, spreadsheets, slide generation
- Duration: 15 minutes per module
Document Verification
All candidates must attend with original certificates: educational qualifications, caste certificate (if applicable), experience certificates, and ID proof.
Failing Tier 4 disqualifies you from final selection even after clearing three tiers. The typing speed requirement eliminates 8-10% of otherwise qualified candidates annually.

Frequently Asked Questions
Is SSC CGL Tier 1 marks counted in final selection?
No. Only Tier 2 marks determine your final rank and post allocation. Tier 1 is purely for screening—cross the cutoff and your marks reset. Your combined Tier 2 score (Papers 1+2, with 3:1 weightage if applicable) decides your merit position. However, Tier 3 and Tier 4 are qualifying stages you must clear.
Can I skip Tier 2 Paper 3 if I'm not applying for Statistical posts?
Yes, absolutely. Paper 3 (Statistics) is mandatory only for Statistical Investigator and Compiler positions. If you're targeting any other post like Tax Assistant, Auditor, or Inspector, you only need to appear for Paper 1 and Paper 2 in Tier 2. Appearing for Paper 3 unnecessarily wastes time.
What happens if I qualify Tier 2 but fail Tier 3?
You're eliminated from SSC CGL 2025 selection completely. Tier 3 is qualifying—you must score minimum 33 marks (General category) regardless of your excellent Tier 1-2 performance. Your marks don't contribute to final merit, but failing means no document verification, no final selection. Practice descriptive writing seriously for at least 2-3 months.
How is normalization calculated in SSC CGL Tier 1 and Tier 2?
SSC uses a normalization formula across multiple exam shifts to ensure fairness. The formula considers: your raw score, average score of your shift, average score of all shifts, and highest score across shifts. If your shift had a tougher paper, normalization adjusts your score upward. You cannot calculate it yourself—focus on maximizing raw score instead.
Do I need to practice typing speed even for non-Tax Assistant posts?
Only if you're applying for specific posts requiring DEST (Tax Assistant) or CPT (CSS Assistant, Inspector roles). Check the detailed post requirements in the SSC CGL Post Preference Guide. For posts like Auditor, JSO, or Statistical Investigator, no typing test exists—you proceed directly to document verification after clearing Tier 3.
Conclusion: Master the Pattern, Crack the Exam
The SSC CGL exam pattern 2025 tests you across four distinct stages—each eliminating thousands of unprepared candidates. Your strategy should match this structure: dominate Tier 1 to qualify, maximize Tier 2 for rank, practice Tier 3 to survive, and prepare Tier 4 skills for specific posts.
Most candidates master Tiers 1-2 but stumble at Tier 3 descriptive writing or Tier 4 typing tests. Start practicing all four components from day one, not just when you clear the previous tier.
