计算器规定
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: Demonstrate knowledge of terms/concepts and explain relations. (23%)
AO2: AO2: Apply knowledge/understanding to various economic contexts. (23%)
AO3: AO3: Analyze issues and construct coherent arguments using data. (27%)
AO4: AO4: Evaluate economic arguments, policies, and make judgments. (27%)

计算器程序
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
用途: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使用时机: Checking solutions, sketching, or solving where an analytic method is hard.
步骤
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考试提示: 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.
Numerical equation solver
Graphical calculator / GDC (exam mode)
用途: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使用时机: Iterative or implicit equations, or to confirm an algebraic solution.
步骤
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考试提示: 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.
Numerical integration & differentiation
Graphical calculator / GDC (exam mode)
用途: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使用时机: Checking calculus answers, or where only a numerical value is needed.
步骤
Use the GDC's numeric integral / derivative function with the limits or the point.
考试提示: 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 & probability distributions
Graphical calculator / GDC (exam mode)
用途: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使用时机: Statistics questions and hypothesis tests.
步骤
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考试提示: 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.
常见错误
1high涉及分数: 2Externalities
Omitting explicit labels on the axes and curves of market failure / externality diagrams.
如何避免: Ensure the vertical axis is labeled 'Costs and Benefits', the horizontal is 'Quantity', and individual curves are explicitly labeled as MPB, MSB, MPC, and MSC.
2medium涉及分数: 3Costs
Failing to shift both the average cost (AC) and marginal cost (MC) curves upwards when illustrating a rise in variable costs.
如何避免: Remember that variable costs (such as energy bills or raw materials) affect both average cost and marginal cost. Shift both AC and MC upwards, unlike fixed cost increases which only shift AC.
3medium涉及分数: 2Oligopoly
Calculating concentration ratios incorrectly by summing the wrong top firms, or omitting the final percentage formatting.
如何避免: Identify the market share of the top specified number of firms (e.g., three-firm or four-firm), sum their shares explicitly, and write the final answer in a clear percentage format (e.g., 54.2%).
4high涉及分数: 1Employment and unemployment
Confusing percentage changes with percentage point changes in data interpretation questions.
如何避免: Use 'percentage points' when describing a direct difference between two percentages (e.g., an unemployment rate falling from 5.2% to 3.8% is a fall of 1.4 percentage points, not 1.4%).
5medium涉及分数: 2Taxation
Explaining regressive taxes as ones where the rich pay less money in absolute terms.
如何避免: Define a regressive tax correctly as one where the tax paid represents a smaller proportion/percentage of income as income rises, even if the absolute amount paid is the same or higher.
6high涉及分数: 2The multiplier
Failing to show step-by-step arithmetic working in short quantitative questions, risking zero marks if the final value is misrounded.
如何避免: Always write out your complete formula and intermediate calculation steps. If you make a minor rounding slip, examiners can still award process marks.
