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: Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures. (32%)
AO2: Apply knowledge and understanding of scientific ideas, processes, techniques and procedures. (42%)
AO3: Analyse, interpret and evaluate scientific information, ideas and evidence. (26%)
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: 2Limitation of physical measurements
Selecting small coordinate gradient triangles (less than 50% of the grid size) for graphical analysis in Paper 3.
如何避免: Always construct your gradient calculation triangle to cover more than 50% of the line of best fit on both axes.
2medium涉及分數: 1Radioactivity
Omitting the '+' sign between products in nuclear decay and reaction equations (e.g., separating the daughter nucleus and the alpha particle).
如何避免: Clearly write nuclear equations using standard notation, ensuring products are explicitly separated with a '+' sign.
3high涉及分數: 2Force, energy and momentum
Directly multiplying force by parallel distance in moments calculations instead of identifying and resolving the perpendicular distance.
如何避免: Identify the hinge/pivot point, trace the line of action of the force, and resolve the perpendicular component of distance or force.
4medium涉及分數: 2Force, energy and momentum
Forgetting to include the weight of a uniform rigid beam acting at its midpoint in equilibrium moments equations.
如何避免: Always draw a free-body diagram representing the beam's weight acting downwards at the exact geometric center before taking moments.
5high涉及分數: 2Thermal physics
Using temperatures in Celsius instead of Kelvin in gas laws or thermal equations.
如何避免: Convert Celsius temperatures to Kelvin immediately by adding 273.15 before performing any calculations.
6medium涉及分數: 1Limitation of physical measurements
Plotting graphs with feathered, sketchy, or double lines.
如何避免: Use a sharp pencil and draw a single, clean, continuous line of best fit directly through the plotted data.
7high涉及分數: 2Limitation of physical measurements
Failing to convert metric prefixes (e.g., mm, mV, microseconds) to standard SI units when evaluating experimental intercepts or gradients.
如何避免: Read the axis scale labels carefully and convert standard prefixes (e.g., milli = 10^-3) before evaluating calculation constants.
8high涉及分數: 1Limitation of physical measurements
Rounding intermediate calculation values too early, which pushes the final answer outside of the acceptable range.
如何避免: Keep unrounded values stored in the calculator's memory and perform rounding only on your final output step.
9medium涉及分數: 2Progressive and stationary waves
Attempting to use the wave equation (v = f * lambda) to determine the speed of sound in a rod instead of calculating the pulse travel time and distance.
如何避免: Differentiate between propagating wave pulse speed (v = d/t) and continuous standing wave calculations before selecting your formulas.
10medium涉及分數: 2Limitation of physical measurements
Confusing percentage uncertainty with absolute uncertainty when calculating or drawing error bars.
如何避免: Absolute uncertainty is represented by physical dimensions on graph grids, whereas percentage uncertainty is absolute uncertainty divided by the value, multiplied by 100.
