SSC CGL CBI SI Exam Pattern 2026 – Tier 1 & Tier 2
The SSC CGL CBI SI selection process consists of:
- Tier 1 – Computer-Based Test (Qualifying)
- Tier 2 – Computer-Based Test (Merit-Deciding)
- Document Verification + Physical Standards Check
There is no Tier 3 (Descriptive Paper) and no Physical Efficiency Test (PET) for the CBI SI post. Final merit is based entirely on Tier 2 performance.
SSC CGL CBI SI 2026 Tier 1 Exam Pattern
- Sectional Timing (New 2026): Each section locks after exactly 15 minutes — you cannot move between sections or use leftover time.
- Negative Marking: 0.5 marks deducted per wrong answer.
- Purpose: Qualifying only — Tier 1 marks are not counted in the final merit list.
- Mode: Computer-Based Test (CBT) at designated SSC exam centres.
- Language: Bilingual (Hindi & English) — except English Comprehension section.
| Section | Questions | Marks | Time |
|---|---|---|---|
| General Intelligence & Reasoning | 25 | 50 | 15 min |
| General Awareness | 25 | 50 | 15 min |
| Quantitative Aptitude | 25 | 50 | 15 min |
| English Comprehension | 25 | 50 | 15 min |
| Total | 100 | 200 | 60 min |
SSC CGL CBI SI 2026 Tier 2 Exam Pattern:
Paper 1 – Compulsory for all posts including CBI SI:
| Section | Module | Questions | Marks | Negative Marking |
|---|---|---|---|---|
| Section I | Mathematical Abilities | 30 | 90 | 1 mark |
| Section I | Reasoning & General Intelligence | 30 | 90 | 1 mark |
| Section II | English Language & Comprehension | 45 | 135 | 1 mark |
| Section II | General Awareness | 25 | 75 | 1 mark |
| Section III (Module I) | Computer Knowledge Test | 20 | 60 | Qualifying |
| Section III (Module II) | Data Entry Speed Test (DEST) | — | Qualifying | N/A |
Critical Note for CBI SI Aspirants:
The Computer Knowledge Test is qualifying only — its marks are not added to your merit score. Your final rank for the CBI SI post is based solely on Section I and Section II performance (360 marks total).
SSC CGL CBI Sub Inspector Mock Test 2026 – Why It Matters
Clearing SSC CGL and specifically targeting the CBI SI post requires a different preparation mindset than simply qualifying Tier 1. Since the CBI SI cut-off is among the highest post-wise cut-offs in the entire SSC CGL exam, you need scores that are significantly above the general qualifying threshold.
1. Replicate the High-Stakes Pressure
The CBI SI post is fiercely competed — with thousands of candidates targeting the same preference. Mock tests train your mind to perform under pressure, maintaining accuracy and speed simultaneously.
2. Master the New Sectional Timing
The 2026 update mandates strict 15-minute locks per section in Tier 1, and section-wise timers in Tier 2 as well. Mock tests based on this updated pattern are the only way to build the muscle memory needed to handle these constraints.
3. Build Tier 2 Accuracy
With 1-mark negative marking per wrong answer in Tier 2, one reckless attempt can cost you 2 marks (0 for the question + 1 deducted). Practising on mock tests specifically calibrated for Tier 2 difficulty helps you develop the right guessing threshold.
4. Benchmark Against Competitors
Quality mock test platforms show your All-India percentile rank, helping you understand where you stand relative to other CBI SI aspirants — not just average CGL candidates.
5. Identify Your Score Gap
If CBI SI requires a Tier 2 score of 480+ out of 450+ and you are scoring 420 in mocks, you know exactly how much to improve and in which sections.
How to Attempt SSC CGL CBI SI Mock Test 2026 – Guidelines
Use this 3-phase mock test plan specifically designed for CBI SI aspirants:
Phase 1: Baseline Assessment (Week 1–2)
- Take 2–3 full-length Tier 1 mock tests without any preparation.
- Identify your natural strengths and biggest weak spots.
- Do not get discouraged by the score — this is just a diagnostic.
Phase 2: Sectional Focus (Month 1–2)
- Attempt chapter-wise tests after completing each topic.
- Aim for minimum 80% accuracy in each chapter test before moving on.
- Take 1 sectional mock per subject per week (Reasoning, Quant, English, GK).
Phase 3: Full-Length Mock Test Regime (Month 3–Exam)
- Attempt 1 full-length Tier 1 mock every alternate day.
- After clearing Tier 1 level, start 1 Tier 2 full mock every 3 days.
- The 2x Review Rule: Spend double the test time reviewing your answers.
Subject-Wise Mock Test Strategy for CBI SI Aspirants
Because the CBI SI cut-off is among the highest in the CGL exam, your sectional targets in mock tests must be more ambitious than for average CGL posts.
Quantitative Aptitude – Target: 22+/30 in Tier 2
- The CBI SI aspirant cannot afford to be weak in Maths.
- Focus on Data Interpretation, Algebra, Mensuration, and Trigonometry — these carry the most Tier 2 weight.
- Practise calculation-speed drills: aim to solve each Quant question in under 90 seconds.
- In mock tests, attempt the easiest 20 questions first, then return to complex ones.
Reasoning – Target: 26+/30 in Tier 2
- This is the most rewarding section for CBI SI candidates — high accuracy is very achievable.
- Practise Coding-Decoding, Analogy, Series, and Syllogism daily.
- Non-verbal reasoning (Figures, Embedded Images) takes time — allocate 15–18 minutes for this module in Tier 2 mocks.
English – Target: 36+/45 in Tier 2 (The Section That Separates CBI SI Ranks)
- English has 45 questions in Tier 2 — the single biggest section.
- A CBI SI aspirant must read English newspapers daily (Hindu, Indian Express).
- In mock tests, prioritize: RC Passages > Cloze Test > Sentence Improvement > Vocabulary.
- Target accuracy of 80%+ in RC-based questions.
General Awareness – Target: 20+/25 in Tier 2
- GK is non-calculative — maximum reward for study time invested.
- For CBI SI specifically, pay extra attention to Indian Polity, Legal Acts, Crime Investigation Laws, and RTI/CBI Act — these are directly relevant to the job profile and occasionally appear in GK.
- Follow a monthly current affairs capsule religiously.
SSC CGL CBI SI Cut Off Marks – Previous Year Trends
The CBI SI post-wise cut-off is significantly higher than the general SSC CGL cut-off due to intense competition and fewer vacancies for this specific post.
Tier 1 Cut Off Trends (General All-Posts Reference):
| Year | UR | OBC | SC | ST | EWS |
|---|---|---|---|---|---|
| 2025 | 136.83 | 130.36 | 114.97 | 106.36 | 127.41 |
| 2024 | ~145–150 | ~135–140 | ~120–125 | ~110–115 | ~135–140 |
| 2023 | ~142–148 | ~133–138 | ~118–124 | ~108–114 | ~133–138 |
Tier 2 Final Cut Off – CBI SI (Post-Specific, Indicative):
| Year | UR | OBC | SC | ST |
|---|---|---|---|---|
| 2024 | ~480–500 | ~455–470 | ~420–440 | ~400–420 |
| 2023 | ~470–490 | ~450–465 | ~415–430 | ~395–415 |
With 12,256 total vacancies in 2026 (reduced from ~14,582 in 2025), CBI SI cut-offs in Tier 2 are expected to rise by 10–15 marks across all categories.
Common Mistakes to Avoid in SSC CGL CBI Sub Inspector Mock Test 2026
These errors specifically affect CBI SI aspirants more than average CGL candidates:
1. Not Tracking Post-Wise Cut-Off Targets
Many candidates practise to “clear” SSC CGL rather than targeting the CBI SI cut-off specifically. Always benchmark against post-specific cut-offs, not just qualifying scores.
2. Ignoring the Tier 2 Negative Marking Severity
With 1 full mark deducted per wrong answer in Tier 2, a wrong attempt in Tier 2 costs you 2 effective marks (1 for the question + 1 penalty).
3. Weak English in Tier 2
Many Hindi-medium aspirants underestimate English in Tier 2. With 45 questions at 135 marks, poor English performance alone can push you below the CBI SI cut-off even if Quant and Reasoning are strong.
4. Skipping Physical Fitness Preparation
Candidates focus entirely on the written exam and neglect physical standards. Start height/chest measurement verification and basic fitness maintenance early.
5. Not Analysing Mock Test Performance Post-Attempt
Taking mock tests without analysis is like practising for a music concert and never listening to the recording.
Frequently Asked Questions
How many mock tests should I take specifically for CBI SI preparation?
Since CBI SI demands scores well above the qualifying cut-off, aim for a minimum of 40–50 Tier 1 mock tests and 25–30 Tier 2 mock tests
Where can I find free SSC CGL CBI SI model question paper PDFs?
Free model papers are available on platform like Entri. Always verify that the paper is based on the 2026 exam pattern with sectional timing before practising.
