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.
AO1: Recall, select and use their knowledge of mathematical facts, concepts and techniques. (50%)
AO2: Construct rigorous mathematical arguments and proofs through use of precise statements, logical deduction and inference. (30%)
AO3: Recall, select and use their knowledge of standard mathematical models to solve problems. (20%)

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: 2Algorithms on graphs
In D1, failing to write down the final node when specifying the nearest neighbour route (e.g., stopping at J instead of returning to A).
回避方法: Always close the circuit by appending the start node to the very end of your final listed route (e.g., A - B - C - F - E - J - A).
2high影響する配点: 3Dynamics of a particle moving in a straight line or plane
Omitting the gravitational acceleration component 'g' when resolving forces or moments in Mechanics (M1/M2).
回避方法: Audit your equations of motion: verify that every weight term has 'g' included (e.g., '24g' instead of '24') and that mass terms in 'ma' do not.
3medium影響する配点: 2Algorithms on graphs II
Writing values at each node out of chronological or strictly decreasing order in Dijkstra's algorithm.
回避方法: Always write down the values at each node in the exact order they are calculated. Ensure they are listed strictly from left to right as you inspect incoming paths.
4high影響する配点: 3Integration
Omission of the arbitrary constant (+ c) during indefinite integration, especially in multipart differential equations.
回避方法: As soon as you remove the integration symbol, write '+ c' immediately on that line. Never wait until substituting boundary conditions.
5high影響する配点: 3The Normal distribution
Failing to apply the continuity correction (+/- 0.5) when transitioning from discrete binomial/Poisson distributions to Normal approximations.
回避方法: Sketch a discrete bar chart to visualize the inequality. If you need P(X < 20) for discrete X, the Normal approximation must use P(Y < 19.5).
6low影響する配点: 5Critical path analysis
In CPA networks, drawing precedence diagrams using 'Activity on Node' instead of the required 'Activity on Arc'.
回避方法: Draw activities as labeled lines (arcs) and events as numbered circles (nodes). Any Activity on Node diagram will score zero in this exam.
