计算器规定
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, theories and models. (28%)
AO2: AO2: Apply knowledge and understanding to various economic contexts. (28%)
AO3: AO3: Analyse economic issues, showing relationships between variables. (22%)
AO4: AO4: Evaluate economic arguments, policies and actions. (22%)

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, 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)
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, 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)
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, 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)
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
常见错误
1high涉及分数: 2Aggregate supply (AS)
Labeling macroeconomic diagram axes as 'Price' and 'Quantity' on AD/AS models.
如何避免: Always label the vertical axis as 'Price Level' (or Average Price Level) and the horizontal axis as 'Real Output' or 'Real GDP'.
2high涉及分数: 1National income
Omitting the word 'billion' or currency symbols (such as '$') in final calculated answers.
如何避免: Always check the extract's unit scaling and write the full final answer out. If calculating a multiplier change of 3.9 billion with a multiplier of 10, write '$39 billion' or '$39,000,000,000', not just '39'.
3medium涉及分数: 4Measures of economic performance
Conflating disinflation with deflation during data interpretation questions.
如何避免: Remember that disinflation is a fall in the rate of inflation (prices are still rising, but more slowly), whereas deflation is a negative rate of inflation (average prices are absolute falling).
4high涉及分数: 4Macroeconomic objectives and policies
Writing purely theoretical Section D essays without applying the arguments to a specific chosen country.
如何避免: Structure your answers with explicit reference to real economies (e.g., Singapore for free markets, Egypt for monetary policy, or Guyana for economic development). Theoretical-only essays are capped to Level 3.
5medium涉及分数: 2Government intervention in markets
Drawing a pivoted supply curve rather than a parallel leftward shift to represent a specific unit indirect tax.
如何避免: A specific unit tax shifts the supply curve vertically upwards, remaining perfectly parallel. Only ad valorem taxes pivot from the origin or horizontal intercept because the absolute tax value is a percentage of price.
6high涉及分数: 2Market failure
Omitting the welfare loss triangle or drawing it in the incorrect direction pointing away from the social optimum in externality diagrams.
如何避免: Draw the welfare loss triangle pointing directly towards the socially optimum level of output (the intersection of MSC and MSB) to represent overprovision/underprovision.
7medium涉及分数: 2Consumer behaviour and demand
Neglecting to write down the formula or show intermediate step calculations in price elasticity (PED/YED/XED) questions.
如何避免: Always state the formula first, e.g. % change in Quantity Demanded / % change in Price, and show your percentage changes individually to secure method marks in case of simple arithmetic errors.
