Examiner Tips

Expert advice for maximising your marks

💡In Paper 2 essays, explicitly use the sustainability compass (nature, economy, society, wellbeing) to structure balanced arguments and demonstrate holistic thinking.
💡For Data-Based Questions, always interpret trends by linking them to environmental processes or human actions, not just describing the data—refer to units, scale, and anomalies.
💡Build a mental library of well-researched, contrasting case studies for major themes (e.g., climate change adaptation in Bangladesh vs. Netherlands) to draw upon flexibly.

Common Mistakes

Pitfalls to avoid in your exam answers

Students often describe environmental impacts in isolation, neglecting to analyse how societal factors such as culture, politics, or economics shape both causes and solutions.
A frequent error is misusing systems concepts, for example confusing open and closed systems or failing to distinguish between transfer and transformation processes.
Many learners rely on generic case studies without adapting them to the specific question, resulting in superficial analysis that lacks place-specific detail or data.
