Expected Weightage
The Common University Entrance Test (CUET) for Ecology and Environment assesses students’ understanding of environmental science, biodiversity, conservation, and sustainability. Below is an analysis of the last 3 years’ (2021-2023) marking pattern and chapter-wise weightage based on trends observed in previous exams.
1. Overall Marking Pattern (2021-2023)
- Total Questions: 50 (out of which 40 must be attempted)
- Marks per Question: +5 for correct, -1 for incorrect
- Total Marks: 200 (40 × 5)
- Exam Duration: 45 minutes
Note: The exact pattern may vary slightly year-to-year, but the general structure remains consistent.
2. Chapter-wise Weightage (Trend Analysis)
Based on past trends, the most important chapters and their approximate weightage are:
| Chapter | Weightage (2021-2023) | Key Topics |
|---|---|---|
| Ecosystems | 20-25% | Structure, functions, energy flow, ecological pyramids, nutrient cycles |
| Biodiversity Conservation | 18-22% | Types of biodiversity, hotspots, threats, conservation methods (in-situ ex-situ) |
| Environmental Pollution | 15-20% | Air, water, soil pollution; waste management; greenhouse effect; ozone depletion |
| Climate Change Global Issues | 12-15% | Global warming, Kyoto Protocol, Paris Agreement, carbon footprint |
| Natural Resources Sustainability | 10-12% | Renewable non-renewable resources, sustainable development goals (SDGs) |
| Environmental Laws Policies | 8-10% | Wildlife Protection Act, EPA 1986, international conventions (CITES, Ramsar) |
| Human Population Environment | 5-8% | Population growth, urbanization, health impacts |
3. Year-wise Trends (2021-2023)
- 2021: More focus on biodiversity ecosystems (30% weightage).
- 2022: Increased questions on climate change pollution (25% combined).
- 2023: Balanced distribution, with laws policies gaining slightly more weight (12%).
Observation: - Ecosystems Biodiversity remain the highest-scoring areas. - Current environmental issues (e.g., climate change, waste management) are gaining importance. - Application-based questions (case studies, data interpretation) are increasing.
4. Preparation Tips
- Focus Areas: Ecosystems, biodiversity, pollution, and climate change (~70% weightage).
- Revise Laws Policies: Acts like Wildlife Protection Act, EPA 1986 frequently appear.
- Practice Diagrams Flowcharts: Questions on ecological pyramids, carbon cycle are common.
- Stay Updated: Recent global environmental summits (COP28, SDGs) may be asked.
Conclusion
The CUET Ecology Environment paper has a balanced distribution , with Ecosystems, Biodiversity, and Pollution being the most critical sections. Recent years show a slight shift toward applied environmental science rather than just theoretical concepts.
