SSC CGL Mains Subjects 2025 (Tier 2): In-Depth Subject & Topic Analysis

You've cleared the first hurdle. Now, the real challenge begins. This in-depth guide dissects the subjects of the SSC CGL Mains exam, giving you the clarity needed to conquer the final stage.

Congratulations on clearing the SSC CGL Tier 1! That’s a significant achievement, but as any seasoned player will tell you, the qualifying rounds are just a warm-up. The Mains (Tier 2) is the championship match. This is where the competition intensifies, the questions deepen, and your true mettle is tested. The scores you get here are what will ultimately decide your post and your future.

Unlike the fast-paced, 60-minute sprint of the Prelims, the Mains is a marathon of endurance and deep conceptual knowledge. The syllabus might look familiar, but the approach required is fundamentally different. It's no longer just about speed; it's about depth, precision, and the ability to handle complex problems under pressure. Let's break down the structure and subjects of this crucial stage to build your definitive battle plan.

The New Battlefield: Understanding the SSC CGL Mains Exam Structure

The SSC CGL Mains exam consists of three papers. Paper I is compulsory for all posts. Paper II and Paper III are for specialized posts only.

Paper I (Compulsory for All Posts)

This is the main event. It is divided into three sections, which are further split into modules. Each question carries 3 marks, and there is a negative marking of 1 mark for each wrong answer.

Paper II & Paper III (For Specific Posts)

• Paper II - Statistics: For candidates who apply for the Junior Statistical Officer (JSO) post.
• Paper III - General Studies (Finance and Economics): For candidates who apply for Assistant Audit Officer (AAO) / Assistant Accounts Officer (AAO) posts.

Dissecting Paper I: A Module-by-Module Subject Analysis

Let's go deeper into the subjects of the compulsory Paper I, which will determine the rank for most aspirants.

Module I: Mathematical Abilities

This is where your quantitative skills face their ultimate test. While the topics overlap with Tier 1, the difficulty level takes a significant leap. Questions are more complex, often combining multiple concepts, and require a deeper understanding of fundamentals rather than just shortcut tricks.

• Arithmetic: The core remains the same but with more intricate calculations and multi-step problems. Expect tougher questions from Percentage, Profit & Loss, Time & Work, and CI & SI.
• Advanced Mathematics: This area sees the biggest jump in difficulty.
  • Algebra: Advanced identities, quadratic equations, and algebraic expressions.
  • Geometry: In-depth questions on circles, triangles, chords, tangents, and coordinate geometry.
  • Mensuration: Complex problems involving the volume and surface area of combined solids (e.g., a cone mounted on a hemisphere).
  • Trigonometry: Advanced identities, height and distance problems involving multiple angles.
• New Additions: Topics like **Statistics and Probability** are also part of the Mains syllabus, covering concepts like Mean, Median, Mode, and basic probability.

Module I: Reasoning & General Intelligence

In the Mains, Reasoning moves beyond simple puzzles. The questions are designed to be more time-consuming and test higher-order thinking. Your ability to calmly analyze complex situations is under scrutiny.

• Critical Thinking: Expect more questions on Statement & Assumption, Statement & Conclusion, Course of Action, and Cause & Effect.
• Puzzles: Seating arrangements (circular and linear) and other puzzles become more complex with more variables.
• Non-Verbal Reasoning: While still present, the patterns in figure-based questions can be more subtle and tricky.
• Decision Making & Problem Solving: Questions that present a situation and require you to choose the most logical course of action.

Module II: English Language & Comprehension

With 45 questions, this subject has the highest weightage in Paper I. The focus shifts dramatically from isolated grammar/vocabulary questions to a deep test of your comprehension skills.

• Reading Comprehension: This is the star of the show. Expect multiple passages, including longer, more complex ones, followed by inference-based questions.
• Cloze Test & Para Jumbles: These are also comprehension-based. You'll get longer passages for Cloze Tests and more complex sentences for Para Jumbles.
• Vocabulary: The level of words tested in Synonyms, Antonyms, and One-Word Substitution is higher than in Tier 1.
• Grammar: While direct grammar questions exist, they are often embedded within Sentence Improvement and Error Spotting in longer, more complex sentences. A deep knowledge of advanced grammar rules is essential.

Module II: General Awareness

The GA section in Mains is not just about factual recall; it's about a deeper understanding of the issues. The questions are often more analytical and require you to connect different pieces of information.

• Polity & Economics: These subjects gain more importance. Expect in-depth questions about the Constitution, parliamentary functions, economic policies, and the national budget.
• History & Geography: Questions are less direct and may require you to understand the context and significance of events and geographical features.
• Science & Technology: The focus might shift from general science to recent developments in technology, space, and defense.
• Current Affairs: A thorough understanding of major national and international news is essential.

Module III: Computer Knowledge Test (Qualifying)

This is a new and crucial addition to the Mains. While the marks are not added to the final total, you **must** score the minimum qualifying marks in this section. Failing here means you are out of the race, regardless of your score in other sections.

• Computer Basics: Organization of a computer, CPU, input/output devices, memory, and keyboard shortcuts.
• Software: Basics of Windows Operating System and familiarity with Microsoft Office (MS Word, MS Excel, PowerPoint).
• Working with Internet and E-mails: Basics of networking, web browsing, downloading/uploading, and email management.
• Basics of Networking and Cyber Security: Concepts like viruses, malware, hacking, and preventive measures.

Conclusion: It's a Test of Depth, Not Just Speed

The SSC CGL Mains exam is designed to select the best of the best. It rewards candidates who have moved beyond surface-level preparation and have built a deep, conceptual understanding of each subject. Your strategy must now shift from covering a wide range of topics quickly to mastering the core subjects in-depth. Focus on quality practice, analyze your mistakes in mock tests, and build the endurance to perform at your peak for over two hours. This is the final frontier, and with the right approach, you can conquer it.
