Key examiner messages
Top priorities from the principal examiner before you revise
This series of examinations sits at a balanced, moderate difficulty level (3/5 stars).
While Paper 11 focuses heavily on rigorous scientific recall of physical processes (such as plate tectonics and nuclear fission), Paper 21 demands high competence in practical, context-driven scenario analysis.
Students equipped with strong graphical skills and precise terminology will find many accessible marks, whereas those relying on rote memorisation without conceptual flexibility may struggle with application-heavy questions.

Difficulty Verdict
This series of examinations sits at a balanced, moderate difficulty level (3/5 stars). While Paper 11 focuses heavily on rigorous scientific recall of physical processes (such as plate tectonics and nuclear fission), Paper 21 demands high competence in practical, context-driven scenario analysis. Students equipped with strong graphical skills and precise terminology will find many accessible marks, whereas those relying on rote memorisation without conceptual flexibility may struggle with application-heavy questions.
Where the Marks Are
A substantial portion of the marks in both papers is allocated to data-handling skills, which include completing and plotting bar charts, interpreting trends, and executing multi-step calculations. For instance, Paper 21 dedicated 17 marks to marine species harvesting management, incorporating calculations of percentage increases and graph constructions. Additionally, core topics like Ecosystems and Earthquakes & Volcanoes represented a combined total of 25 marks, highlighting the vital importance of mastering foundational concepts.
Examiner notes & key calculations
- Ignoring Command Specifics: In Paper 11, when asked to explain earthquake mitigation strategies in MEDCs before they occur, many candidates lost marks by writing extensively about post-disaster rescue and recovery operations.
- Mathematical Inversions: In Paper 21, when calculating percentage increases, a common mistake was dividing the difference by the final value rather than the initial value.
- Vague Scientific Terminology: Candidates frequently lost marks on the water cycle diagram by failing to use precise words from the list, such as substituting generic terms for "ground water flow" or "infiltration".
- Logarithmic Richter Scale Misunderstanding: Many students struggled to explain that an earthquake of Richter magnitude 4 is 100 times greater in wave amplitude than one of magnitude 2, often erroneously suggesting it is simply twice as powerful.
