ข้อกำหนดเครื่องคิดเลข
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.
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: 3An introduction to production, costs, revenue and profit
Failing to state the correct mathematical units (e.g. omitting '$bn', '€m', or ratio notation) and performing inaccurate rounding.
วิธีหลีกเลี่ยง: Always intermediate-check the end of the question for formatting requirements. Write final units clearly (e.g. '$13.36bn' instead of '13.36') and round to the exact requested decimal place.
2highคะแนนที่เกี่ยวข้อง: 9Government intervention in markets
Drawing a maximum price above equilibrium, or a minimum price below equilibrium.
วิธีหลีกเลี่ยง: Remember that a maximum price must be a binding cap placed BELOW equilibrium, while a minimum price must be a binding floor placed ABOVE equilibrium.
3mediumคะแนนที่เกี่ยวข้อง: 3Private goods, public goods and quasi-public goods
Using the terms 'non-excludability' and 'non-rivalry' interchangeably, compromising precision on public goods.
วิธีหลีกเลี่ยง: Keep them distinct: non-excludability means you cannot prevent non-payers from consuming; non-rivalry means one person's consumption does not reduce the amount available for others.
4highคะแนนที่เกี่ยวข้อง: 3Fiscal policy
Defining 'investment' in macroeconomics as a purely financial transaction (like saving money in a bank or purchasing shares).
วิธีหลีกเลี่ยง: In macroeconomics, investment must be defined as firm spending on capital goods (physical assets, machinery, and technology used to produce goods and services).
5mediumคะแนนที่เกี่ยวข้อง: 3Price, income and cross elasticities of demand
Omitting the negative sign in elasticity calculations (e.g., Price Elasticity of Demand or Cross Elasticity of Demand for complements).
วิธีหลีกเลี่ยง: Keep the negative sign if your working yields one (e.g., PED = -0.21), as dropping it changes the economic interpretation unless the absolute coefficient is explicitly requested.
6highคะแนนที่เกี่ยวข้อง: 9Market failure and government intervention in markets
Drawing an accurate diagram but failing to reference it or label points (e.g., specific shifts, prices, quantities) in the written text.
วิธีหลีกเลี่ยง: Always weave your diagram labels directly into your analysis. Cite the movement from P1 to P2, output Y1 to Y2, or specifically mention areas representing welfare loss or producer revenue.
7highคะแนนที่เกี่ยวข้อง: 6Measuring economic growth, development and living standards
Providing a one-sided response to Section B Q18.2 instead of using conflicting or contrasting data from the extracts.
วิธีหลีกเลี่ยง: For 'To what extent' questions, use contrasting data points from the extracts (e.g., contrasting high-income with low-income nations) to show that the relationship holds in some cases but not others.
8highคะแนนที่เกี่ยวข้อง: 20Possible conflicts between macroeconomic policy objectives
Under-developing chains of reasoning (transmission mechanisms) in 12-mark and 20-mark essays.
วิธีหลีกเลี่ยง: Never leave gaps in your logic. Write out step-by-step connections showing how a policy changes interest rates or spending, how that shifts AD or AS, and how that impacts the final macroeconomic indicators.
