ข้อกำหนดเครื่องคิดเลข
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 of terms/concepts and explain relations. (23%)
AO2: AO2: Apply knowledge/understanding to various economic contexts. (23%)
AO3: AO3: Analyze issues and construct coherent arguments using data. (27%)
AO4: AO4: Evaluate economic arguments, policies, and make judgments. (27%)
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 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)
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 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)
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 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)
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 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.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 2Externalities
Omitting explicit labels on the axes and curves of market failure / externality diagrams.
วิธีหลีกเลี่ยง: Ensure the vertical axis is labeled 'Costs and Benefits', the horizontal is 'Quantity', and individual curves are explicitly labeled as MPB, MSB, MPC, and MSC.
2mediumคะแนนที่เกี่ยวข้อง: 3Costs
Failing to shift both the average cost (AC) and marginal cost (MC) curves upwards when illustrating a rise in variable costs.
วิธีหลีกเลี่ยง: Remember that variable costs (such as energy bills or raw materials) affect both average cost and marginal cost. Shift both AC and MC upwards, unlike fixed cost increases which only shift AC.
3mediumคะแนนที่เกี่ยวข้อง: 2Oligopoly
Calculating concentration ratios incorrectly by summing the wrong top firms, or omitting the final percentage formatting.
วิธีหลีกเลี่ยง: Identify the market share of the top specified number of firms (e.g., three-firm or four-firm), sum their shares explicitly, and write the final answer in a clear percentage format (e.g., 54.2%).
4highคะแนนที่เกี่ยวข้อง: 1Employment and unemployment
Confusing percentage changes with percentage point changes in data interpretation questions.
วิธีหลีกเลี่ยง: Use 'percentage points' when describing a direct difference between two percentages (e.g., an unemployment rate falling from 5.2% to 3.8% is a fall of 1.4 percentage points, not 1.4%).
5mediumคะแนนที่เกี่ยวข้อง: 2Taxation
Explaining regressive taxes as ones where the rich pay less money in absolute terms.
วิธีหลีกเลี่ยง: Define a regressive tax correctly as one where the tax paid represents a smaller proportion/percentage of income as income rises, even if the absolute amount paid is the same or higher.
6highคะแนนที่เกี่ยวข้อง: 2The multiplier
Failing to show step-by-step arithmetic working in short quantitative questions, risking zero marks if the final value is misrounded.
วิธีหลีกเลี่ยง: Always write out your complete formula and intermediate calculation steps. If you make a minor rounding slip, examiners can still award process marks.
