Master the Oxford AQA International A-level Business (9625) exams with this expert-compiled guide. Learn how to construct deep logical chains for 9-mark analytical questions, structure balanced Level 4 evaluations for 12-mark essays, and avoid costly calculation and formatting slip-ups on quantitative questions across all four units.
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: Demonstrate knowledge of terms, concepts, theories, methods and models (24%)
AO2: Apply knowledge and understanding to various business contexts (25%)
AO3: Analyse issues within business, showing cause-and-effect impact (23%)
AO4: Evaluate quantitative and qualitative information to make informed judgements (28%)

電卓プログラム
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
目的: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使う場面: Checking solutions, sketching, or solving where an analytic method is hard.
手順
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
試験での注意: 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)
目的: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使う場面: Iterative or implicit equations, or to confirm an algebraic solution.
手順
Use the equation/zero solver, entering the equation and a sensible starting estimate.
試験での注意: 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)
目的: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使う場面: Checking calculus answers, or where only a numerical value is needed.
手順
Use the GDC's numeric integral / derivative function with the limits or the point.
試験での注意: 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)
目的: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使う場面: Statistics questions and hypothesis tests.
手順
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
よくあるミス
1high影響する配点: 1Financial data
Omitting the percentage sign (%) or currency symbols in quantitative calculation answers (e.g., stating ARR as '5' instead of '5%').
回避方法: Double-check the specific formatting rules for the formula being evaluated. Always include '%' for ARR, ROCE, and profit margins, and currency units for payback or cash flow.
2high影響する配点: 3Choosing strategic direction
Failing to build deep, sequential chains of cause and effect in 9-mark analytical questions.
回避方法: Do not just list benefits or drawbacks. Ensure you construct a multi-stage logical sequence of consequences showing the exact pathway to final business profits or competitive advantage.
3high影響する配点: 4Managing strategic change
Evaluating strategic options with generic textbook pros/cons rather than linking directly to the specific case study context.
回避方法: Avoid abstract statements. Always base your arguments on the specific details of the case, such as the company's real liquidity levels, geographical settings, or target demographics.
4medium影響する配点: 6Mission, objectives and strategy
Writing a one-sided essay for 12-mark questions, which limits the candidate's score to Level 2.
回避方法: Always present at least one robust argument for and one robust argument against before presenting a justified recommendation in your conclusion.
Omitting the initial investment outlay subtraction when calculating the financial appraisal figures for Average Rate of Return (ARR).
回避方法: Ensure you calculate the net profit first: Total Cash Inflows over the lifetime of the project minus the Initial Cost. Divide this Net Profit by the number of years before dividing by the initial investment.
6high影響する配点: 2Financial data
Failing to write down intermediate formulas or working processes when calculating financial metrics like Payback or Gearing.
回避方法: Always show every line of math. If your final calculated figure is incorrect due to a keystroke error, examiners can still award partial marks using the Own Figure Rule (OFR).
