Topic Wise Weightage (Based on Previous Years)
The Science section in SSC CGL, especially within the General Awareness portion of Tier 1 and Tier 2, is a key scoring area. Questions are asked to test a candidate's basic understanding of Physics, Chemistry, Biology, and Environmental Science, often from a practical or day-to-day perspective. While the level is generally up to 10th standard, Tier 2 may involve slightly deeper application-based questions. Knowing the topic-wise weightage from previous years can help aspirants prioritize their preparation and focus on high-yield areas. Here's a breakdown based on analysis of past SSC CGL papers:
| Subject | Approx. Number of Questions | Remarks |
|---|
| Biology | 3–4 Questions | High-weightage; focuses on human body, diseases, cells, nutrition, genetics |
| Physics | 2–3 Questions | Based on motion, heat, light, sound, work & energy concepts |
| Chemistry | 2–3 Questions | Questions come from atomic structure, acids & bases, carbon compounds, metals |
| Environment | 1–2 Questions | Topics include ecology, pollution, biodiversity, sustainable development |
Note: The number of questions may vary slightly in each shift, but this weightage is based on analysis of the last 5 SSC CGL exams.

Tips to Prepare SSC CGL Science Syllabus Effectively
The Science section of the SSC CGL General Awareness syllabus may seem vast, but with a smart and structured approach, it becomes one of the easiest scoring areas. Most of the questions are based on basic concepts from classes 6th to 10th, especially from NCERT textbooks. Regular revision, conceptual clarity, and practicing previous year questions are the keys to mastering this section. Follow these effective tips to boost your preparation and confidently tackle science questions in both Tier 1 and Tier 2:
- Start with NCERTs (6th–10th): Focus on concepts rather than memorizing facts blindly.
- Make Notes by Subject: Maintain separate short notes for Physics, Chemistry, Biology & Environment.
- Revise Science in Blocks: Dedicate one day each to Physics, Chemistry, and Biology in your weekly plan.
- Watch Concept Videos: Use YouTube or learning apps for visual understanding (e.g., Human Digestive System, Reflection of Light).
- Solve Previous Year Papers: Most science questions are repeated or twisted from past years.
- Focus on Static Science: Avoid over-preparing dynamic or too advanced science topics not asked in Tier 1.
