電卓の規定
A scientific or graphical calculator that meets JCQ regulations may be used (some GCSE Mathematics and Science papers are non-calculator). Graphical calculators must be set to exam mode; you must clear any stored programs, notes or data before the exam, and the calculator must not be able to retrieve stored text or formulae.
AO1: AO1: Use and apply standard techniques (50%)
AO2: AO2: Reason, interpret and communicate mathematically (25%)
AO3: AO3: Solve problems within mathematics and in other contexts (25%)

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 under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
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 under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
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 under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
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 under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
よくあるミス
1high影響する配点: 2Solving equations and inequalities (Algebra)
Squaring negative numbers incorrectly by typing or writing -4^2 = -16 instead of (-4)^2 = 16.
回避方法: Always place negative numbers inside brackets when squaring them: (-4) x (-4) = 16. On calculators, type '(-4)^2'.
2medium影響する配点: 1Measures and accuracy (Number)
Failing to round up in real-life discrete contexts, such as calculating 7.2 teachers needed for a trip and giving 7 as the answer.
回避方法: Identify real-world constraints: 7 teachers would leave some students unsupervised. Always round up to the next integer (8) in capacity or safety contexts.
3high影響する配点: 3Statistics (Statistics)
Confusing 360 degrees with 100 percent when calculating angles or drawing sectors for pie charts.
回避方法: Always use 360 degrees as the total denominator for circle calculations. Divide the category frequency by the total population, then multiply by 360.
4high影響する配点: 1Measures and accuracy (Number)
Premature rounding of intermediate decimals, leading to a slight discrepancy in the final digit of multi-step calculator problems.
回避方法: Keep intermediate values written in exact form (like fractions or multiples of pi) or store them in your calculator memory, rounding only the very final value.
5medium影響する配点: 1Structure and calculation (Number)
Writing invalid monetary notations such as £4.2 instead of standard £4.20.
回避方法: Always express sterling currency to exactly two decimal places when pence are involved. Write £4.20 to meet examiner standards.
6medium影響する配点: 2Measures and accuracy (Number)
Attempting to perform decimals estimation by computing the exact product first and then rounding, which wastes valuable time and increases arithmetic risk.
回避方法: Round each number in the question to 1 significant figure first (e.g., 31 becomes 30, and 18 becomes 20), then perform the simple multiplication (30 x 20 = 600).
