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%)
วัตถุประสงค์: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
ใช้เมื่อใด: Checking solutions, sketching, or solving where an analytic method is hard.
ขั้นตอน
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
ใช้เมื่อใด: Iterative or implicit equations, or to confirm an algebraic solution.
ขั้นตอน
Use the equation/zero solver, entering the equation and a sensible starting estimate.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
ใช้เมื่อใด: Checking calculus answers, or where only a numerical value is needed.
ขั้นตอน
Use the GDC's numeric integral / derivative function with the limits or the point.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
ใช้เมื่อใด: Statistics questions and hypothesis tests.
ขั้นตอน
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
ข้อควรระวังในการสอบ: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 3Measuring economic growth, development and living standards
Omitting correct currency units ($, £, ¥), percentage signs, or denominations (billions, millions) in calculation questions.
วิธีหลีกเลี่ยง: 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.
2mediumคะแนนที่เกี่ยวข้อง: 3Price, income and cross elasticities of demand
Forgetting to specify the negative sign in Price Elasticity of Demand (PED) calculations.
วิธีหลีกเลี่ยง: 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.
3highคะแนนที่เกี่ยวข้อง: 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.
วิธีหลีกเลี่ยง: 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.
4highคะแนนที่เกี่ยวข้อง: 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.
วิธีหลีกเลี่ยง: 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.
5mediumคะแนนที่เกี่ยวข้อง: 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.
วิธีหลีกเลี่ยง: 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.
6mediumคะแนนที่เกี่ยวข้อง: 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).
วิธีหลีกเลี่ยง: 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.
7highคะแนนที่เกี่ยวข้อง: 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.
วิธีหลีกเลี่ยง: 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.
