電卓の規定
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.

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: 3Changing cities
Failing to explicitly name and locate a real-world city (such as Bristol, Mumbai, or Rio de Janeiro) in the Changing Cities essay responses.
回避方法: Always mention your studied city case studies by name on high-tariff essays, integrating at least three specific local facts, policies, or demographic statistics to lift your response into the higher mark bands.
2high影響する配点: 2Geographical investigations − UK challenges
Using vague evaluation adjectives like 'cheaper', 'easier', or 'quicker' on Paper 3 without structural or geographic elaboration.
回避方法: Explain the physical, economic, or logistical mechanism behind the cost/benefit. For example, explain how using local soft-engineering materials like marram grass planting reduces high capital import costs.
3high影響する配点: 2Weather hazards and climate change
Failing to extract specific quantitative values from graphs to support analytical statements (e.g., Sahel rainfall variations or Holderness erosion rates).
回避方法: Always practice extracting minimum, maximum, or change values directly from the figures provided. Cite these exact numbers and years directly in your written response.
4medium影響する配点: 4Global development
Losing SPaG marks on high-tariff essays due to spelling errors in complex geographical terms.
回避方法: Create a dedicated spelling glossary during your revision for high-risk terms like 'desalination', 'hydroelectric', 'eutrophication', and 're-urbanisation' to protect your 4 SPaG marks.
5medium影響する配点: 2Global development
Providing circular or mirrored explanations for developmental indicators, such as stating GNI causes development because the country becomes more developed.
回避方法: Provide the precise sequential steps of the mechanism. E.g., explain that higher GNI increases government tax yields, which are reinvested into healthcare infrastructure, lowering infant mortality.
Omitting units (such as 'mm', '%', or 'Mha') in mathematical calculation questions.
回避方法: Always scan the final answer line to see if the unit is pre-printed. If it is not, write down the unit immediately alongside your final calculated number.
7medium影響する配点: 1Ecosystems, biodiversity and management
Misclassifying 'wood' as an abiotic resource or 'soil' as a biotic resource due to confusion between biological and physical ecosystem components.
回避方法: Remember that 'biotic' represents living or organic components (e.g., plants, animals, bacteria) while 'abiotic' represents non-living, physical components (e.g., soil, rock, water, sunlight).
8low影響する配点: 2Coastal landscapes and processes
Believing that constructive waves erode beaches, rather than building them up.
回避方法: Understand that constructive waves have a strong swash and a weak backwash, which deposits sediment on the beach, whereas destructive waves have a strong backwash that erodes the beach.
9high影響する配点: 2Geographical investigations – Investigating human environments
Assuming random sampling in fieldwork guarantees a perfectly representative sample of your study area.
回避方法: Recognize that random sampling can lead to geographic clustering, leave large areas unsampled, or direct students to unsafe and inaccessible locations.
