電卓の規定
A graphic display calculator (GDC) from the IB-approved list is required for most Mathematics and Sciences papers and must be set to examination mode. Note that some papers do not permit a calculator (for example Mathematics Paper 1 and the multiple-choice Sciences Paper 1).
AO1: AO1 Knowledge and understanding
AO2: AO2 Application and analysis
AO3: AO3 Synthesis and evaluation
AO4: AO4 Use and application of appropriate skills

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: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
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: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
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: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
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: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
よくあるミス
1high影響する配点: 2Break-even analysis
Omitting currency symbols ($/£) or physical unit labels (e.g., 'spaces', 'units', 'dresses') in final calculations.
回避方法: Always check the required units of the final value and append them clearly (e.g., writing '$95' instead of '95', or '60 spaces' instead of '60').
2high影響する配点: 1Cash flow
Labeling the final row of a cash-flow forecast as 'net profit' instead of 'net cash flow'.
回避方法: Keep cash and profit concepts distinct. Cash flows track liquid balances, whereas profit is calculated on a Statement of Profit or Loss. Always use 'Net Cash Flow', followed by 'Opening Balance' and 'Closing Balance'.
3medium影響する配点: 2Costs and revenues
Formulating circular definitions (e.g., defining 'variable costs' as 'costs that vary' or 'cost-plus pricing' as 'adding a plus to costs').
回避方法: Define technical terms using distinct, precise characteristics. For example, 'variable costs are costs that change in direct proportion to the level of output/activity'.
4high影響する配点: 5Business objectives
Providing one-sided arguments in Section B 10-mark recommendation or discussion questions.
回避方法: Structure essays to analyze both advantages and disadvantages of each option (at least two 'for' and two 'against' arguments) before making a balanced conclusion.
5medium影響する配点: 2Break-even analysis
Drawing break-even charts freehand, resulting in imprecise intersections or messy lines.
回避方法: Always use a clear plastic ruler to draw cost, revenue, and fixed cost lines. Ensure both axes are fully labeled, with the y-axis showing 'Costs and Revenues' (both terms) and the x-axis indicating physical units.
6medium影響する配点: 2Decision Trees
Failing to include the decision node, chance nodes, key, or double slashes (//) indicating rejected options on decision tree diagrams.
回避方法: Construct the tree using standard symbols: squares for decision points, circles for chance nodes. Calculate Expected Values clearly, draw double slashes through the lower-yielding path, and provide a clear key.
7medium影響する配点: 2Final accounts
In Statement of Profit or Loss construction, omitting key layout components such as interest, tax, or dividends.
回避方法: Follow the standardized IB template strictly: Sales Revenue -> Cost of Sales -> Gross Profit -> Expenses -> Net Profit Before Interest and Tax -> Interest -> Net Profit Before Tax -> Tax -> Profit for the Period -> Dividends -> Retained Profit.
8high影響する配点: 2Business objectives
Failing to address limitations or missing information in high-tariff evaluation questions, capping the mark below the top band.
回避方法: Explicitly state what data is missing from the case study (e.g., competitor reactions, long-term market research, or exact setup costs) that could alter your strategic recommendation.
