Master AQA AS Level Economics 7135 with our expert exam-tips package. Grounded in actual examiner reports, this guide covers strategic time management, constructing flawless analytical chains, avoiding diagram traps, and executing contextual evaluations for maximum marks.
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 theories
AO2: AO2: Apply knowledge and understanding to various economic contexts
AO3: AO3: Analyze economic issues, showing logical chains of reasoning
AO4: AO4: Evaluate economic arguments and make informed judgements
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: 1How the macroeconomy works : the circular flow of income, AD/AS analysis, and related concepts
Failing to state exact numerical units (£, p, billion, €, %) in quantitative calculation answers.
วิธีหลีกเลี่ยง: Always check your final value and write down the relevant symbol. For example, write '€25' instead of '25' or '£431' instead of '431'.
2mediumคะแนนที่เกี่ยวข้อง: 2How the macroeconomy works : the circular flow of income, AD/AS analysis, and related concepts
Drawing microeconomic axes labels on macroeconomic diagrams or vice versa.
วิธีหลีกเลี่ยง: On AD/AS diagrams, strictly label the vertical axis as 'Price Level' (not 'Price') and the horizontal axis as 'Real GDP' or 'Real National Output' (not 'Quantity').
3highคะแนนที่เกี่ยวข้อง: 2The measurement of macroeconomic performance
Treating comparative features in data questions as isolated, separate descriptions.
วิธีหลีกเลี่ยง: Directly contrast the two data series within the same sentence using comparative language (e.g., 'while', 'whereas') and cite explicit data points for both to secure the comparison marks.
4mediumคะแนนที่เกี่ยวข้อง: 1Price determination in a competitive market
Writing a formula instead of a conceptual definition for concepts like Price Elasticity of Demand.
วิธีหลีกเลี่ยง: Define the concept in words (e.g. 'the responsiveness of quantity demanded to a change in price') rather than relying solely on the formula.
5highคะแนนที่เกี่ยวข้อง: 4The market mechanism, market failure and government intervention in markets
Truncating logical chains on the 10-mark 'Explain' questions by jumping straight to final outcomes.
วิธีหลีกเลี่ยง: Write step-by-step sequential links. Explain how one variable directly impacts the next, closing the entire loop back to the economic policy target.
6highคะแนนที่เกี่ยวข้อง: 2The measurement of macroeconomic performance
Confusing disinflation (a slowing rate of price increases) with deflation (a sustained fall in the average price level).
วิธีหลีกเลี่ยง: Remember that during disinflation, prices are still rising, just at a slower rate. Deflation means negative inflation where prices are falling.
7mediumคะแนนที่เกี่ยวข้อง: 2How the macroeconomy works : the circular flow of income, AD/AS analysis, and related concepts
Shifting Aggregate Demand (AD) instead of Short-Run Aggregate Supply (SRAS) when showing indirect tax changes.
วิธีหลีกเลี่ยง: Indirect taxes (like VAT) increase firms' costs of production, so they cause a leftward shift of the SRAS curve, not a movement of the AD curve.
