A scientific or graphical calculator that meets JCQ regulations may be used (some GCSE Mathematics and Science papers are non-calculator). Graphical calculators must be set to exam mode; you must clear any stored programs, notes or data before the exam, and the calculator must not be able to retrieve stored text or formulae.
AO1: AO1: Demonstrate knowledge of locations, places, processes, environments and concepts (22.5%)
AO2: AO2: Demonstrate geographical understanding of concepts and interrelationships (27.5%)
AO3: AO3: Apply knowledge and understanding to interpret, analyse and evaluate geographical information (32.5%)
AO4: AO4: Select, adapt and use a variety of skills including quantitative and fieldwork skills (17.5%)

電卓プログラム
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
目的: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使う場面: Solving or sketching a function when you want to find where its graph crosses or turns.
手順
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
目的: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使う場面: Any data-handling, statistics, or required-practical analysis question.
手順
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
目的: Keep full-precision intermediate values to avoid rounding errors.
使う場面: Multi-step calculations where premature rounding loses the final accuracy mark.
手順
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
目的: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使う場面: As a check only, after solving by hand.
手順
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
試験での注意: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
よくあるミス
1high影響する配点: 1Challenges of an urbanising world
Forgetting to round calculation answers to exactly one decimal place as explicitly requested in the prompt.
回避方法: Circle the rounding instruction on your exam paper. Write the full unrounded calculation out first, then write your final rounded answer to 1 decimal place with units.
2medium影響する配点: 4Hazardous Earth
Confusing the natural physical causes of climate change with human-induced enhanced greenhouse effects.
回避方法: Clearly distinguish astronomical factors (e.g. Milankovitch orbital cycles) and geological factors (volcanic ash/dust blocking solar radiation) from modern human activities (fossil fuels, deforestation).
3medium影響する配点: 2Geographical investigations - Investigating coastal change and conflict
Failing to explicitly link fieldwork data limitations to specific data collection timings (e.g. Saturday morning snapshots).
回避方法: State how the specific day or time of your data collection created a biased, non-representative sample of the environmental or demographic reality.
4high影響する配点: 4Challenges of an urbanising world
Providing generic answers to megacity and case-study questions without referencing specific named locations or local statistics.
回避方法: Always use named case-study locations (e.g., Dharavi in Mumbai, Makoko in Lagos) and specific data points rather than general descriptions of urban poverty.
5high影響する配点: 3Consuming energy resources
Failing to structure extended responses (8- and 12-mark questions) with a clear balance of positive and negative points prior to making a judgment.
回避方法: Plan a two-sided argument before writing. State your main argument in paragraph one, contrast it in paragraph two, and deliver a definitive judgment in your conclusion.
6medium影響する配点: 1The UK’s evolving human landscape
Failing to show step-by-step mathematical working out on percentage calculations, losing partial method marks if the final answer is wrong.
回避方法: Always write down the full formula: ((New - Old) / Old) x 100, show your substitution steps, and then write the final answer clearly.
7medium影響する配点: 4Geographical investigations - Investigating coastal change and conflict
Evaluating the strengths and weaknesses of a fieldwork plan without direct reference back to the actual enquiry question itself.
回避方法: Constantly tie every strength or weakness back to how it affects the reliability, validity, and overall accuracy of the data needed to answer that specific enquiry.
8medium影響する配点: 3Consuming energy resources
Struggling to differentiate between physical causes of economic decline (such as volcanic eruptions/storms) and human/global economic factors on Paper 3.
回避方法: Categorize your factors strictly. Physical causes relate to natural hazards and climate, while human factors involve debt, international trade, and political relationships.
9high影響する配点: 2Challenges of an urbanising world
Lacking numerical evidence when describing relationships in scatter graphs or correlations.
回避方法: Always quote specific data coordinates (e.g., x-axis values and y-axis percentages) for at least two points on the graph to prove the correlation.
10high影響する配点: 6Consuming energy resources
Failing to make a clear, justified choice between Option 1, 2, and 3 in the final Paper 3 essay, ending with an ambiguous, non-committal conclusion.
回避方法: State your chosen option clearly in the opening sentence. Systematically justify it using resource evidence and explicitly reject the remaining options.
