SSC CHSL Reasoning Questions

How to Prepare Reasoning Question for SSC CHSL Exam?

1. Understand the Syllabus Thoroughly

Before you begin any preparation, knowing the complete reasoning syllabus is non-negotiable. The SSC CHSL Reasoning section includes both verbal and non-verbal questions, and questions are framed to test logical thinking, pattern recognition, and analytical skills. 

While some topics are asked frequently, SSC has a habit of mixing easy and tricky questions from across the syllabus. So, skipping any topic just because it appears less often is not a good strategy. Instead, you should aim to build basic familiarity with all topics and then go deeper into the most important ones.

• The reasoning syllabus includes topics like Analogy, Classification, Coding-Decoding, Series (Alphabet and Number), Blood Relations, Direction Sense, Venn Diagrams, and Order and Ranking.

• Non-verbal reasoning topics such as Mirror Images, Water Images, Paper Folding, Embedded Figures, and Matrix-based questions are also important.

• Logical reasoning topics like Syllogism, Statement and Conclusion, and Alphabet Test should not be ignored as 1–2 questions are usually asked.

2. Know the Exam Pattern and Marking Scheme

Understanding the structure of the exam helps you manage both your preparation and real-time performance better. In SSC CHSL Tier 1, the General Intelligence (Reasoning) section has 25 questions of 2 marks each. This section is part of a 100-question paper, with a total time limit of 60 minutes and no sectional timings. For every wrong answer, 0.50 marks are deducted, making accuracy critical. Keeping this in mind, your goal should be to solve as many correct answers as possible without falling into the trap of guesswork.

• Each reasoning question carries +2 marks, and a wrong answer leads to a deduction of 0.50 marks.

• There are no sectional cut-offs, but time must be managed across four sections evenly.

• Solving all 25 reasoning questions within 15–18 minutes will give you enough time for other sections.

3. Focus on Important Topics First

While the entire syllabus is important, SSC tends to repeat questions from certain topics, making them highly scoring if prepared well. These include Analogy, Classification, Alphabet Series, Coding-Decoding, Blood Relations, Order and Ranking, and Direction Sense. A strong grip on these areas can help you attempt at least 15–18 questions quickly with high accuracy. 

• Begin preparation with frequently asked topics like Series, Coding-Decoding, and Analogy.

• Allocate separate time blocks for visual reasoning (Mirror Images, Paper Folding), as they are also regularly asked.

• Use topic-wise practice sets to master patterns and identify common traps.

4. Make a Timed Practice Schedule

SSC CHSL is a speed-based test, and completing 100 questions in 60 minutes requires fast decision-making. To master this, you need to set a realistic timetable that involves timed practice on reasoning questions. 

• Practise at least 20–30 reasoning questions every day under timed conditions.

• Initially, practise without a timer to build conceptual clarity, then shift to timed sessions.

5. Use Previous Year Papers and Mock Tests

Previous year papers give you a true sense of the exam’s difficulty level, question patterns, and commonly repeated topics. SSC often repeats logic types and formats, so solving PYQs (Previous Year Questions) is a must. Once you have enough command over individual topics, start taking full-length mock tests. 

• Solve at least the last 5–7 years' SSC CHSL reasoning questions to observe trends.

• Attempt one full mock test every week and increase the frequency as the exam approaches.

• Analyse the mock tests thoroughly to understand mistakes and improve them.

• Maintain a notebook to write down difficult or confusing questions for future revision.

6. Avoid Guesswork and Focus on Accuracy

Due to the negative marking system in SSC CHSL, it’s risky to attempt questions based purely on guesswork. While some reasoning questions may look easy at first, they often contain hidden logic that can be missed under pressure. 

• Avoid attempting a question unless you’re 100% sure of the logic and answer.

• Always recheck your answer for direction, order, or position-based questions before submitting.

7. Use the Right Study Materials and Books

Choosing the right books and practice sources can save you time and give you the right direction. Don’t overload yourself with multiple resources. Focus on standard books that are popular for SSC exams and include sufficient SSC-style questions. You can consider the below books

8. Revise Regularly and Monitor Your Progress

Regular revision is key to avoiding confusion during the exam. Even if you’ve solved hundreds of questions from a topic, make sure to revisit them after a few weeks. Along with revision, it’s important to track your own performance over time.
