計算機規定
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%)
根據歷屆試題與評分準則整理（2022–2024）。
計算機程式
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
用途: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使用時機: Checking solutions, sketching, or solving where an analytic method is hard.
步驟
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考試提示: 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)
用途: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使用時機: Iterative or implicit equations, or to confirm an algebraic solution.
步驟
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考試提示: 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)
用途: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使用時機: Checking calculus answers, or where only a numerical value is needed.
步驟
Use the GDC's numeric integral / derivative function with the limits or the point.
考試提示: 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)
用途: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使用時機: Statistics questions and hypothesis tests.
步驟
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考試提示: 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.
常見錯誤
1high涉及分數: 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.
如何避免: 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 write down cell references when explaining spreadsheet models (e.g. capacitor discharge columns).
如何避免: Write down the exact cell math (such as G11 = F11/B11) rather than raw numerical values or general labels like 'charge divided by resistance'.
3high涉及分數: 3Thermodynamics (Concept-led approach)
Failing to convert initial values to standard SI units (e.g., using millimeters in resistivity or Celsius in thermal speed calculations).
如何避免: Convert temperature to Kelvin by adding 273.15, and convert lengths from millimeters or centimeters to meters before substituting into equations.
4high涉及分數: 1Working as a Physicist (Concept-led approach)
Drawing excessively small triangles when evaluating the gradient of a curve or tangent line.
如何避免: Construct a large gradient triangle on your line of best fit that covers at least 50% of the active axis span.
5high涉及分數: 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.
如何避免: 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).
如何避免: 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涉及分數: 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.
如何避免: 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涉及分數: 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'.
如何避免: 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涉及分數: 1Working as a Physicist (Concept-led approach)
Assuming that repeating measurements and calculating a mean reduces systematic errors.
如何避免: 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涉及分數: 2Materials (Concept-led approach)
Believing that upthrust on a closed gas canister decreases when gas is released.
如何避免: 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.
