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: Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures. (35%)
AO2: Apply knowledge and understanding of scientific ideas, processes, techniques and procedures. (40%)
AO3: Analyse, interpret and evaluate scientific information, ideas and evidence, make judgements and reach conclusions. (25%)

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: 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.
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: 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.
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: 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 & 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: 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: 2Mechanical properties of materials
Converting cubic millimeters to cubic meters by dividing by 10^3 (or multiplying by 10^-3) instead of dividing by 10^9 (multiplying by 10^-9).
回避方法: Convert each dimension of the unit: since 1 mm = 10^-3 m, (1 mm)^3 = (10^-3 m)^3 = 10^-9 m^3. Apply this full scale factor for conversions.
2medium影響する配点: 3Sensing
Failing to account for the internal resistance of a battery when explaining potential divider outputs under a load.
回避方法: Always calculate the total circuit resistance first, including the internal resistance (r). The terminal potential difference is given by V = E - Ir, which decreases as current increases.
3high影響する配点: 2Imaging and signalling
Drawing wavefronts passing through a converging lens with straight lines or incorrect curvature directions.
回避方法: Ensure wavefronts emerging from a converging lens curve inwards toward the principal focus, maintaining perpendicularity to converging rays by eye.
4high影響する配点: 1Waves and quantum behaviour
Truncating numbers prematurely during multi-step calculations, leading to rounding errors in final values like photon numbers.
回避方法: Store full unrounded values in your calculator's memory registers during intermediate steps. Round only your final answer to the correct number of significant figures.
5medium影響する配点: 2Mechanical properties of materials
Using the wire diameter directly in the area formula A = pi * r^2 instead of dividing by 2 to find the radius.
回避方法: Always calculate radius as diameter / 2 before squaring, or use the alternative area formula: A = (pi * d^2) / 4.
6high影響する配点: 1Fundamental data analysis
Failing to write down the intermediate unrounded calculated value in 'show that' questions before presenting the final rounded target.
回避方法: Explicitly write the raw calculator value to 3 or 4 significant figures first, then write a final line: 'approx. equal to [target value]'.
7medium影響する配点: 1Sensing
Writing lowercase coordinates (e.g., c2) or omitting the '*' operator when constructing requested spreadsheet computational formulas.
回避方法: Always use uppercase letters for cell names and explicit operators, e.g., `=C2+(B2*0.10)` to avoid syntax mark deductions.
8high影響する配点: 2Fundamental data analysis
Drawing gradient triangles or tangents that are too small (covering less than half of the plotted range of the graph data).
回避方法: Ensure that your gradient triangle spans at least 50% of the horizontal or vertical axis grid length to secure full precision marks.
