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: Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures (30%)
AO2: AO2: Apply knowledge and understanding of scientific ideas, processes, techniques and procedures (40%)
AO3: AO3: Analyse, interpret and evaluate scientific information, ideas and evidence, including in relation to issues, to make judgements and reach conclusions and develop and refine practical design and procedures (30%)

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: 2Working as a Physicist (Concept-led approach)
Failing to double the percentage uncertainty of a diameter/radius when propagating it into circular cross-sectional areas or spherical volumes.
回避方法: Since area \(A = \frac{\pi d^2}{4}\), the percentage uncertainty in area is equal to \(2 \times \%\Delta d\). Always multiply the diameter's percentage uncertainty by 2 before adding it to other uncertainties.
Failing to convert initial values to standard SI units (e.g., using millimeters in resistivity or Celsius in thermal speed calculations).
回避方法: Convert temperature to Kelvin by adding 273.15, and convert lengths from millimeters or centimeters to meters before substituting into equations.
4high影響する配点: 1Working as a Physicist (Concept-led approach)
Drawing excessively small triangles when evaluating the gradient of a curve or tangent line.
回避方法: Construct a large gradient triangle on your line of best fit that covers at least 50% of the active axis span.
5high影響する配点: 2Electric and Magnetic Fields (Concept-led approach)
Failing to state 'rate of change of magnetic flux linkage' in electromagnetic induction questions, opting instead for vague descriptions.
回避方法: Always state that a changing current/motion causes a 'rate of change of magnetic flux linkage', which induces an e.m.f. according to Faraday's law.
Omitting key reaction forces or leaving out clear directional arrows in free-body diagrams (e.g. reaction forces from support columns).
回避方法: Ensure all force vectors are drawn with straight lines, start exactly at the boundary or center of mass, point in the true force direction, and are explicitly labelled.
7high影響する配点: 1Working as a Physicist (Concept-led approach)
Failing to write down intermediate algebraic substitution steps in multi-mark 'show that' questions, rendering numerical outputs ineligible for full marks.
回避方法: Always show the full formula, the values substituted with their powers of 10, and write down an unrounded intermediate answer before stating the final rounded 'show that' value.
8medium影響する配点: 2Working as a Physicist (Concept-led approach)
Confusing the term 'precision' (closeness of repeated measurements) with 'resolution' (smallest division on a measuring tool) or 'accuracy'.
回避方法: Learn the precise definitions: precision relates to the spread of repeated readings, resolution to the measuring scale, and accuracy to the closeness to the true value.
9medium影響する配点: 1Working as a Physicist (Concept-led approach)
Assuming that repeating measurements and calculating a mean reduces systematic errors.
回避方法: Clearly state that repeating measurements only mitigates the effect of random errors and helps identify anomalies; systematic errors (like zero errors or calibration shift) are unaffected.
10low影響する配点: 2Materials (Concept-led approach)
Believing that upthrust on a closed gas canister decreases when gas is released.
回避方法: Remember that upthrust depends strictly on the volume of fluid displaced. Since the canister's physical volume remains constant, the upthrust remains constant, but the mass of gas inside decreases, making the canister lighter.
