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: 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%)

计算器程序
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
用途: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使用时机: Solving or sketching a function when you want to find where its graph crosses or turns.
步骤
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
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 mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
用途: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使用时机: Any data-handling, statistics, or required-practical analysis question.
步骤
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
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.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
用途: Keep full-precision intermediate values to avoid rounding errors.
使用时机: Multi-step calculations where premature rounding loses the final accuracy mark.
步骤
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
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.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
用途: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使用时机: As a check only, after solving by hand.
步骤
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
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: 2Price stability
Confusing a decline in the positive rate of inflation (disinflation) with a fall in price levels (deflation).
如何避免: 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涉及分数: 1Supply
Failing to draw a continuous line to join plotted coordinate points on demand or supply curves.
如何避免: 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涉及分数: 2The role of money and financial markets
Misinterpreting fractional percentage values (such as 0.01% or 0.2%) during interest rate calculations as integers.
如何避免: Convert fractional percentages to decimals by dividing by 100 first (e.g. 0.2% = 0.002) before performing multiplications.
4high涉及分数: 1Production
Forgetting to apply currency symbols (£ or $) or unit suffixes (such as 'millions' or 'billions') to final calculation values.
如何避免: 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涉及分数: 1Supply
Defining only the root word (e.g. 'supply') rather than the full term requested (e.g. 'decrease in supply') in 2-mark definitions.
如何避免: 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涉及分数: 3Globalisation
Failing to explicitly reference the specific country, business, or region mentioned in Section B case extracts.
如何避免: 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涉及分数: 1Production
Losing intermediate marks by presenting only the final numerical calculation answer with no shown workings.
如何避免: 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涉及分数: 3Fiscal policy
Omitting a logical, multi-step chain of reasoning (AO3a) linking policy changes to final macroeconomic impacts in 6-mark analysis questions.
如何避免: Construct a coherent pathway using connectives like 'consequently', 'this leads to', and 'as a result' to link initial policy actions to ultimate outcomes.
9high涉及分数: 3Supply side policies
Failing to offer a balanced evaluation with benefits, costs, and a supported final judgement in 6-mark asterisk (*) questions.
如何避免: 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.
