计算器规定
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: AO1 - Recall, select and communicate knowledge and understanding of commercial terms, concepts and issues (26.3%)
AO2: AO2 - Apply knowledge and understanding of commercial terms, concepts and issues to various contexts (37.5%)
AO3: AO3 - Deconstruct and analyse commercial information and issues (18.1%)
AO4: AO4 - Evaluate commercial information and issues to make judgements and draw conclusions (18.1%)

计算器程序
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
用途: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使用时机: Solving or sketching a function when you want to find where its graph crosses or turns.
步骤
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
用途: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使用时机: Any data-handling, statistics, or required-practical analysis question.
步骤
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
用途: Keep full-precision intermediate values to avoid rounding errors.
使用时机: Multi-step calculations where premature rounding loses the final accuracy mark.
步骤
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
用途: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使用时机: As a check only, after solving by hand.
步骤
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
常见错误
1high涉及分数: 2Retail (Commercial Operations)
Failing to apply generic concepts to context in State and Outline questions, using generic terms like 'product' rather than specific nouns like 'vegetable sauces', 'sarees', or 'sweets'.
如何避免: Always incorporate specific nouns from the case study extract (e.g. mention 'silk sarees' for Pothys or 'handmade sweets' for Candy Wonderland) to secure AO2 marks.
2high涉及分数: 1Commercial calculations (Finance for Commerce)
Failing to round calculation results (e.g., currency conversions, profit margin, or discounted values) to exactly two decimal places as requested.
如何避免: Read the rounding prompt carefully and always express final numeric figures rounded to two decimal places (e.g., 21.56% or 33603.75).
3medium涉及分数: 6Improving commercial performance (Finance for Commerce)
Using bullet points or brief numbered lists in high-tariff 9-mark or 12-mark questions.
如何避免: Write in full, continuous prose with developed logical chains of reasoning, linking points with connectives like 'therefore', 'this means that', and 'consequently' to reach Level 3 marks.
4medium涉及分数: 4Improving commercial performance (Finance for Commerce)
Describing both options on 9-mark 'Justify' questions instead of structuring a balanced argument and analytical comparison.
如何避免: Structure your essay with one body paragraph evaluating the pros and cons of the chosen option, a second paragraph comparing it critically to the rejected option, and a final justified recommendation.
5medium涉及分数: 1Insurance (Commercial Risks)
Confusing professional roles in commerce, such as mistaking the duties of an insurance assessor for those of an insurance actuary.
如何避免: Remember that actuaries work before loss occurs (calculating risk and setting premiums), whereas assessors/adjusters evaluate claims post-loss.
6high涉及分数: 1Commercial calculations (Finance for Commerce)
Forgetting to show clear mathematical workings inside calculation boxes, losing process marks when a calculation error occurs.
如何避免: Write down the formula first, substitute the numbers clearly, and state your intermediate working steps to ensure partial marks can be awarded.
