電卓の規定
A silent scientific calculator is required where the syllabus permits one. It must NOT be graphical, programmable, or capable of symbolic algebra (CAS), and it must contain no stored programs or notes.
AO1: Recall, select and use mathematical facts, concepts and techniques (45%)
AO2: Construct rigorous mathematical arguments and proofs (35%)
AO3: Translate situations into mathematical models and solve problems (20%)

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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
よくあるミス
1high影響する配点: 2Differentiation
Forgetting to divide the derivative of dy/dx with respect to t by dx/dt when applying the parametric chain rule for second derivatives.
回避方法: Always write down the formula: d2y/dx2 = [d/dt(dy/dx)] / (dx/dt) as the first step of your working to ensure you divide by dx/dt.
2high影響する配点: 3Hooke's law
Squaring the difference of extensions (x1 - x2)^2 instead of calculating the difference of squared extensions (x1^2 - x2^2) in Elastic Potential Energy equations.
回避方法: EPE change is always the final EPE minus the initial EPE: lambda * (x_final^2 - x_initial^2) / (2l). Treat EPE values as individual states rather than squaring the net displacement.
3high影響する配点: 3χ2-test
Failing to combine classes in Chi-squared tests when the expected frequencies fall below 5, invalidating the test statistic and degrees of freedom.
回避方法: Check all expected frequencies before computing the test statistic. If any expected frequency is < 5, merge that class with an adjacent one, then recalculate the degrees of freedom.
4medium影響する配点: 1Non-parametric tests
Defining hypotheses for Wilcoxon signed-rank or rank-sum tests using population mean (mu) instead of population median (m).
回避方法: Always write hypotheses for non-parametric tests in terms of the population median: H0: m_A = m_B (or m_difference = 0) and define m explicitly in context.
5high影響する配点: 2Non-parametric tests
Omitting the necessary continuity correction (+/- 0.5) when using the normal approximation to calculate the Wilcoxon test statistic.
回避方法: When standardising the rank sum T to find the z-value, apply the continuity correction to the numerator: z = (|T - E(T)| - 0.5) / sqrt(Var(T)).
6medium影響する配点: 3Circular motion
Assuming a particle in vertical circular motion on a string loses contact when its velocity is zero, rather than when the tension/normal reaction becomes zero.
回避方法: Set the normal reaction force R = 0 (or tension T = 0) to find the boundary of complete circular motion, and link this boundary to your energy equations.
7medium影響する配点: 2Summation of series
Removing the 1/k factor for ease of writing when computing partial fractions but forgetting to multiply it back in the final answer of the sum of the series.
回避方法: Write down the multiplier 1/k outside the summation brackets on every line of your working so it is not lost in the final limit evaluation.
