評価段階
A*ABCDEU
電卓の規定
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.
過去問と採点基準にもとづいて作成（2023–2026）。
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, 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)
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, 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)
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, 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)
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
よくあるミス
1high影響する配点: 2Mechanics, Materials, and Thermodynamics
Failing to convert standard prefix units (e.g., mm, cm, ms, g, MeV) into base SI units before substitute-calculating.
回避方法: Convert all prefixes (e.g. mm to m, ms to s, g to kg, MeV to J) at the very start of your working before carrying out algebraic manipulations.
2high影響する配点: 1General Physics Calculations
Losing accuracy on 'Show that' questions by not showing unrounded intermediate values before the final rounded result.
回避方法: State the initial algebraic equation, show the raw substitutions, write down the unrounded intermediate value (to at least 3-4 s.f.), and then write the final rounded answer.
3high影響する配点: 2Practical Skills in Physics
Drawing a gradient triangle that is too small when calculating experimental gradients from graphs.
回避方法: Ensure the gradient triangle spans at least 50% of the drawn line of best fit on your graph, and clearly label the vertex coordinates used.
4medium影響する配点: 2Materials and Practical Skills
Forgetting to double the percentage uncertainty of variables that are squared in a formula (e.g., area d^2, or time t^2).
回避方法: Apply the fractional uncertainty power rule: %U(x^n) = n * %U(x). For squared quantities, always multiply the individual percentage uncertainty by 2.
5high影響する配点: 2Mechanics
Misidentifying weight and normal contact force (or weight and magnetic forces) as Newton's Third Law force pairs.
回避方法: Newton's Third Law pairs must act on two different bodies, be of the same type of force, and act in opposite directions. Weight and normal contact force act on the same body.
6medium影響する配点: 1Waves and Particle Nature of Light
Omitting the factor of 2 in round-trip pulse-echo calculations (e.g., radar, sonar, or ultrasound testing).
回避方法: Write down the relationship 2s = v * t for any pulse-echo or round-trip wave scenario to explicitly account for the double journey.
7high影響する配点: 2Thermodynamics
Using temperature values in Celsius instead of absolute Kelvin in ideal gas or thermodynamics kinetic equations.
回避方法: Always convert temperatures to Kelvin using T (K) = theta (C) + 273.15 before substituting values into pV = NkT or mean kinetic energy equations.
