This report details the exact exam structure, common pitfalls, and master strategies for AQA GCSE Economics (8136). It provides a complete diagnostic of both Paper 1 and Paper 2, highlighting key errors such as failing to apply personal allowances, confusing trade and budget deficits, and writing one-sided essays.
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 relationships and explain economic problems (35%)
AO3: AO3: Analyse and evaluate economic data and information to make reasoned judgments (30%)
วัตถุประสงค์: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
ใช้เมื่อใด: Solving or sketching a function when you want to find where its graph crosses or turns.
ขั้นตอน
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
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 mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
วัตถุประสงค์: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
ใช้เมื่อใด: Any data-handling, statistics, or required-practical analysis question.
ขั้นตอน
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
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.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
วัตถุประสงค์: Keep full-precision intermediate values to avoid rounding errors.
ใช้เมื่อใด: Multi-step calculations where premature rounding loses the final accuracy mark.
ขั้นตอน
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
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.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
วัตถุประสงค์: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
ใช้เมื่อใด: As a check only, after solving by hand.
ขั้นตอน
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
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: 2Government income and expenditure
Failing to subtract the initial tax-free personal allowance (e.g. 12,500 or 14,000) before calculating tax liabilities from income tax bracket rates.
วิธีหลีกเลี่ยง: Always calculate taxable income first by subtracting the personal allowance from gross income, then apply the tax percentage rate to the remaining amount.
2highคะแนนที่เกี่ยวข้อง: 3Balance of payments
Confusing a current account trade deficit (imports exceeding exports) with a government budget deficit (expenditure exceeding tax revenue).
วิธีหลีกเลี่ยง: Keep the current account balance separate from government finances. Trade deficit is external/global; budget deficit is national/fiscal.
Shifting the supply curve instead of the demand curve when drawing the impact of complement market price changes on equilibrium (e.g., petrol and petrol cars).
วิธีหลีกเลี่ยง: Complements represent a joint demand relationship. An increase in the price of petrol cars reduces consumer demand for those cars, shifting the demand curve for petrol to the left.
4highคะแนนที่เกี่ยวข้อง: 15Globalisation: benefits and drawbacks
Writing one-sided, unbalanced arguments in 15-mark evaluation essays without introducing a final, reasoned judgment based on context.
วิธีหลีกเลี่ยง: Structure essays with balanced pros and cons, use evidence directly from Item A and Item B, and conclude with a justified, dependent evaluation ('depends on' factors).
5mediumคะแนนที่เกี่ยวข้อง: 2Price elasticity of demand
Omitting the negative sign in price elasticity of demand (PED) calculations or missing clear units (, , billions) in final answers.
วิธีหลีกเลี่ยง: Always check the direction of relationship for PED (typically negative) and ensure units match the data provided in tables.
6mediumคะแนนที่เกี่ยวข้อง: 2Monetary policy
Believing that commercial high street banks have the authority or responsibility to set national interest rates or manage inflation targets.
วิธีหลีกเลี่ยง: Understand that the Bank of England (the central bank) sets the official base rate of interest to control monetary policy and maintain price stability.
7mediumคะแนนที่เกี่ยวข้อง: 9Economies of scale
Failing to calculate average cost (AC) in economies of scale questions when total cost and output figures are provided, preventing candidates from demonstrating cost advantages.
วิธีหลีกเลี่ยง: Always calculate Average Cost (Total Cost / Output) for multiple levels of production to provide objective, numerical evidence of economies or diseconomies of scale.
