計算機規定
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: Demonstrate knowledge and understanding of economic concepts, theories, and policies. (27.5%)
AO2: AO2: Apply knowledge and understanding to various economic contexts. (27.5%)
AO4: AO4: Evaluate economic arguments, policies, and decisions. (22.5%)
根據歷屆試題與評分準則整理（2022–2024）。
計算機程式
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.
使用時機: Checking solutions, sketching, or solving where an analytic method is hard.
步驟
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考試提示: 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.
使用時機: Iterative or implicit equations, or to confirm an algebraic solution.
步驟
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考試提示: 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.
使用時機: Checking calculus answers, or where only a numerical value is needed.
步驟
Use the GDC's numeric integral / derivative function with the limits or the point.
考試提示: 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.
使用時機: Statistics questions and hypothesis tests.
步驟
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考試提示: 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.
常見錯誤
1high涉及分數: 4Inflation
Confusing disinflation (a falling positive rate of inflation) with deflation (a falling average price level below zero) when interpreting CPI trends.
如何避免: Verify the signs on inflation graphs. If the rate of inflation falls from 5% to 2%, the price level is still rising, just at a slower rate. Deflation only occurs when the rate is below 0%.
2high涉及分數: 4Government intervention
Drawing a binding maximum price cap above the free-market equilibrium point, rendering it ineffective.
如何避免: Always locate a binding maximum price cap strictly below the equilibrium point on your supply and demand diagram, showing the resulting excess demand (shortage).
3high涉及分數: 15Externalities
Incorrectly shading the welfare loss triangle in positive or negative externality diagrams.
如何避免: Remember that the welfare loss triangle must always point directly to the socially optimum level of output where MSC = MSB, with its vertical base at the market equilibrium quantity.
4medium涉及分數: 4Price, income and cross elasticities of demand
Omitting intermediate calculation steps, currency symbols, or units in demand elasticity questions.
如何避免: Explicitly show the step-by-step percentage changes, write the full elasticity formula, and state the final answer with its correct sign (negative for PED, positive/negative for YED/XED) and unit labels.
5medium涉及分數: 5Inflation
Relying on generic definitions of CPI without explaining the structural role of weights in indexing relative family expenditures.
如何避免: In explanations of CPI, explicitly mention that weights are assigned based on the Living Costs and Food Survey to ensure that price changes of heavily-purchased items impact the index proportionally.
6high涉及分數: 20Government intervention
Writing purely theoretical answers in Section B high-mark questions, ignoring the sector data provided in the extracts.
如何避免: Incorporate specific numbers, corporate names (e.g., Netflix, Amazon, BBC), and dates from the extracts directly into your analysis to anchor your economic arguments in reality.
