電卓の規定
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%)

電卓プログラム
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
目的: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使う場面: Solving or sketching a function when you want to find where its graph crosses or turns.
手順
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
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 mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
目的: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使う場面: Any data-handling, statistics, or required-practical analysis question.
手順
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
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.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
目的: Keep full-precision intermediate values to avoid rounding errors.
使う場面: Multi-step calculations where premature rounding loses the final accuracy mark.
手順
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
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.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
目的: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使う場面: As a check only, after solving by hand.
手順
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
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: 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'.
回避方法: 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影響する配点: 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.
回避方法: Read the rounding prompt carefully and always express final numeric figures rounded to two decimal places (e.g., 21.56% or 33603.75).
3medium影響する配点: 6Improving commercial performance (Finance for Commerce)
Using bullet points or brief numbered lists in high-tariff 9-mark or 12-mark questions.
回避方法: 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影響する配点: 4Improving commercial performance (Finance for Commerce)
Describing both options on 9-mark 'Justify' questions instead of structuring a balanced argument and analytical comparison.
回避方法: 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影響する配点: 1Insurance (Commercial Risks)
Confusing professional roles in commerce, such as mistaking the duties of an insurance assessor for those of an insurance actuary.
回避方法: Remember that actuaries work before loss occurs (calculating risk and setting premiums), whereas assessors/adjusters evaluate claims post-loss.
6high影響する配点: 1Commercial calculations (Finance for Commerce)
Forgetting to show clear mathematical workings inside calculation boxes, losing process marks when a calculation error occurs.
回避方法: Write down the formula first, substitute the numbers clearly, and state your intermediate working steps to ensure partial marks can be awarded.
