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.
AO1: AO1: Recall, select and communicate knowledge of economic terms, concepts and issues. (35%)
AO2: AO2: Apply knowledge and understanding to highlight the impact of economic issues and the actions of economic agents. (35%)
AO3a: AO3a: Analyse economic issues and laws. (15%)
AO3b: AO3b: Evaluate economic issues and laws, make reasoned judgements and present balanced conclusions. (15%)

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: 2Price stability
Confusing a decline in the positive rate of inflation (disinflation) with a fall in price levels (deflation).
回避方法: Remember that if the rate of inflation decreases but remains positive (e.g. falling from 8.1% to 0.3%), prices are still rising, just at a slower rate. Prices only decrease if inflation is negative.
2medium影響する配点: 1Supply
Failing to draw a continuous line to join plotted coordinate points on demand or supply curves.
回避方法: Always use a sharp pencil and a ruler to draw a solid line connecting all plotted coordinate points. Do not leave them as isolated plotted points on the grid.
3medium影響する配点: 2The role of money and financial markets
Misinterpreting fractional percentage values (such as 0.01% or 0.2%) during interest rate calculations as integers.
回避方法: Convert fractional percentages to decimals by dividing by 100 first (e.g. 0.2% = 0.002) before performing multiplications.
4high影響する配点: 1Production
Forgetting to apply currency symbols (£ or $) or unit suffixes (such as 'millions' or 'billions') to final calculation values.
回避方法: Check the headers of data tables and case extracts. Always include currency symbols and the exact order of magnitude scale in your final answer line.
5medium影響する配点: 1Supply
Defining only the root word (e.g. 'supply') rather than the full term requested (e.g. 'decrease in supply') in 2-mark definitions.
回避方法: Ensure your explanation captures both aspects of the term. For a 'decrease in supply', you must state that it is a shift showing a fall in willingness and ability of producers to sell at each price.
6high影響する配点: 3Globalisation
Failing to explicitly reference the specific country, business, or region mentioned in Section B case extracts.
回避方法: Never write generic textbook essays. Quote numbers, region names (e.g. 'North East of England'), and firm names (e.g. 'The Celandine Hotel') to access higher marks.
7medium影響する配点: 1Production
Losing intermediate marks by presenting only the final numerical calculation answer with no shown workings.
回避方法: Always write down your calculation formulas and intermediate step values. If you make a simple arithmetic slip, you can still gain 1 mark for correct method.
8high影響する配点: 3Fiscal policy
Omitting a logical, multi-step chain of reasoning (AO3a) linking policy changes to final macroeconomic impacts in 6-mark analysis questions.
回避方法: Construct a coherent pathway using connectives like 'consequently', 'this leads to', and 'as a result' to link initial policy actions to ultimate outcomes.
9high影響する配点: 3Supply side policies
Failing to offer a balanced evaluation with benefits, costs, and a supported final judgement in 6-mark asterisk (*) questions.
回避方法: Present a clear argument for both sides, then draw a final judgement that directly addresses the prompt's 'extent to which' based on your preceding analysis.
