A scientific or graphical calculator is permitted. Graphical calculators must be in exam mode with all stored programs and data cleared before the exam; the calculator must not be able to retrieve stored text or formulae.
AO1: AO1: Demonstrate knowledge of terms/concepts and theories/models. (27.5%)
AO2: AO2: Apply knowledge and understanding to various economic contexts. (27.5%)
AO3: AO3: Analyse issues within economics, showing impact on agents. (25%)
AO4: AO4: Evaluate economic arguments and use evidence to support judgements. (20%)

電卓プログラム
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
目的: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使う場面: Checking solutions, sketching, or solving where an analytic method is hard.
手順
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Numerical equation solver
Graphical calculator / GDC (exam mode)
目的: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使う場面: Iterative or implicit equations, or to confirm an algebraic solution.
手順
Use the equation/zero solver, entering the equation and a sensible starting estimate.
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Numerical integration & differentiation
Graphical calculator / GDC (exam mode)
目的: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使う場面: Checking calculus answers, or where only a numerical value is needed.
手順
Use the GDC's numeric integral / derivative function with the limits or the point.
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Statistics & probability distributions
Graphical calculator / GDC (exam mode)
目的: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使う場面: Statistics questions and hypothesis tests.
手順
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
よくあるミス
1high影響する配点: 3Measuring economic growth, development and living standards
Omitting correct currency units ($, £, ¥), percentage signs, or denominations (billions, millions) in calculation questions.
回避方法: Develop a checklist for calculations: always write down the unit specified in the source booklet tables and check if the prompt requires answers in 'billions' or as a raw index value.
2medium影響する配点: 3Price, income and cross elasticities of demand
Forgetting to specify the negative sign in Price Elasticity of Demand (PED) calculations.
回避方法: Always calculate PED as % change in Qd / % change in P. Keep the minus sign explicitly in your final answer unless the question asks for the absolute value.
3high影響する配点: 6Merit and demerit goods
Drawing inaccurate merit and demerit good diagrams where the socially optimum position is incorrectly placed relative to the free market position.
回避方法: For demerit goods, the socially optimum output must be to the left of the free market position (over-consumption/over-production). For merit goods, the socially optimum output must be to the right.
4high影響する配点: 4Economic methodology
Failing to explicitly reference data from Extract A, B, or C in the 6-mark data response questions, leading to a cap on the maximum achievable level.
回避方法: Make it a rule of thumb: quote at least two specific data points (including years, figures, and units) directly from the specified extract to secure full AO2 application marks.
5medium影響する配点: 5The distribution of income and wealth within an economy
Conflating 'wealth' (a stock of accumulated assets) with 'income' (a flow of earnings over time) in inequality essays.
回避方法: Define both terms explicitly in your introduction. State that wealth taxes target the stock of assets, whereas income taxes target the flow of earnings, and analyze their differing impacts on the Gini coefficient.
6medium影響する配点: 2Measuring economic growth, development and living standards
Incorrectly rounding Terms of Trade or GDP per capita calculations (e.g. failing to round to the requested one or two decimal places).
回避方法: Perform your intermediate calculations to 4 decimal places, and round your final answer only at the very end to the exact decimal precision requested by the examiner.
7high影響する配点: 6Aggregate demand and aggregate supply analysis
Lacking a clear, logical chain of reasoning (AO3) in analytical questions, often jumping directly to the final impact without explaining the intermediate transmission steps.
回避方法: Use step-by-step connection words such as 'This causes...', 'Consequently...', 'As a result, this leads to...', ensuring every economic shift is fully explained mechanically.
