计算器规定
A scientific or graphical calculator is permitted. Graphical calculators must be in exam mode with all stored programs and data cleared before the exam; the calculator must not be able to retrieve stored text or formulae.
根据历届试题与评分标准整理（2023–2025）。
计算器程序
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.
使用时机: Checking solutions, sketching, or solving where an analytic method is hard.
步骤
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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.
使用时机: Iterative or implicit equations, or to confirm an algebraic solution.
步骤
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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.
使用时机: Checking calculus answers, or where only a numerical value is needed.
步骤
Use the GDC's numeric integral / derivative function with the limits or the point.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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.
使用时机: Statistics questions and hypothesis tests.
步骤
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
常见错误
1high涉及分数: 3Limitation of physical measurements
Calculating graph gradients using individual raw data points instead of a large construction triangle drawn on the line of best fit.
如何避免: Always draw a construction triangle that spans at least half (ideally 70%) of your line of best fit. Choose coordinates directly from the line of best fit rather than using your original table data points.
2medium涉及分数: 2Radioactivity
Forgetting to subtract background radiation count rate before conducting calculations or plotting inverse-square law relationships.
如何避免: Always measure background count rate first without the source present. Subtract this background rate from your measured count rate to obtain the true, corrected count rate.
3high涉及分数: 1The Young modulus
Omitting the necessary unrounded intermediate value in 'Show that' calculations, leading to lost marks.
如何避免: State the formula, show the substitution, write down the unrounded value from your calculator (to at least 3 significant figures), and then state the rounded final answer.
4high涉及分数: 2Limitation of physical measurements
Failing to convert millimeter or micrometer values to meters when using equations for the Young Modulus or capacitor dimensions.
如何避免: Perform your unit conversions explicitly as the very first step in your calculation (e.g., multiply mm by \( 10^{-3} \) to get meters before squaring or substituting).
5high涉及分数: 1The Young modulus
Confusing the radius and diameter in Young's modulus cross-sectional area calculations, specifically failing to divide the diameter by 2 before squaring.
如何避免: Always double-check if a given dimension is radius or diameter. Write down the explicit step \( r = d/2 \) before using the area formula \( A = \pi r^2 \).
6medium涉及分数: 1Collisions of electrons with atoms
Stating that 'photons have energy levels' instead of correctly identifying that 'atoms have discrete energy levels'.
如何避免: Be precise with terminology. Atoms have discrete energy levels. Photons carry quantized packets of energy equal to the difference between these atomic energy levels: \( \Delta E = hf \).
7medium涉及分数: 1Capacitors
Assuming that inserting a dielectric inside a capacitor connected to a battery changes the potential difference across it.
如何避免: Recognize that if the capacitor remains connected to a battery, the potential difference \( V \) is clamped by the battery and remains constant. Stored charge \( Q \) and capacitance \( C \) increase.
