Paper 2 (Practical Skills, Theory and Multiple Choice)
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: Knowledge and understanding of scientific ideas, processes, techniques and procedures (35%)
AO2: Application of knowledge and understanding of scientific ideas, processes, techniques and procedures (40%)
AO3: Analysis, interpretation and evaluation of scientific information, ideas and evidence (25%)

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 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)
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 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)
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 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)
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 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.
よくあるミス
1high影響する配点: 2Limitation of physical measurements
Failing to convert raw prefix values (e.g. milliseconds in time, millimeters in cable extension) into base SI units before performing calculations.
回避方法: List all variables with their basic SI units (e.g., convert ms to s, mm to m) as the absolute first step of any calculation.
2medium影響する配点: 1Use of SI units and their prefixes
Using nucleon number (mass number A) instead of the actual nuclear mass when calculating the specific charge of a nucleus.
回避方法: Multiply the nucleon number by the atomic mass unit (\(1.66 \times 10^{-27}\text{ kg}\)) or sum the masses of protons and neutrons to get the actual nuclear mass in kilograms.
3high影響する配点: 1Electromagnetic radiation and quantum phenomena
Failing to state that the photoelectric effect involves a precise one-to-one interaction between a single photon and a single electron.
回避方法: Always explicitly state: 'One photon interacts with exactly one electron, transferring all of its energy.'
4high影響する配点: 2Limitation of physical measurements
Drawing a small gradient triangle or thick, inaccurate tangents on line graphs (such as Brinell curves or motion graphs).
回避方法: Draw tangents with a single, sharp pencil line and construct a large right-angled triangle spanning more than half of the tangent line length.
5medium影響する配点: 1Current electricity
Assuming that a potentiometer circuit is just as energy-efficient as a simple series variable resistor circuit.
回避方法: Remember that potentiometers always have current flowing through the entire track to the negative terminal, creating continuous power dissipation even when the output voltage is zero.
