ข้อกำหนดเครื่องคิดเลข
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: AO1: Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures (35%)
AO2: AO2: Apply knowledge and understanding of scientific ideas, processes, techniques and procedures (40%)
AO3: AO3: Analyse, interpret and evaluate scientific information, ideas and evidence (25%)
วัตถุประสงค์: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
ใช้เมื่อใด: Checking solutions, sketching, or solving where an analytic method is hard.
ขั้นตอน
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
ใช้เมื่อใด: Iterative or implicit equations, or to confirm an algebraic solution.
ขั้นตอน
Use the equation/zero solver, entering the equation and a sensible starting estimate.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
ใช้เมื่อใด: Checking calculus answers, or where only a numerical value is needed.
ขั้นตอน
Use the GDC's numeric integral / derivative function with the limits or the point.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
ใช้เมื่อใด: Statistics questions and hypothesis tests.
ขั้นตอน
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
ข้อควรระวังในการสอบ: 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.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 3Waves and quantum behaviour
Assuming the wavelength of a standing wave is equal to the length of the wire or string instead of carefully determining the harmonic mode.
วิธีหลีกเลี่ยง: Always sketch the wave profile to identify nodes and antinodes. For the fundamental frequency on a fixed wire, the wavelength \(\lambda\) is twice the wire length (\(2L\)).
2highคะแนนที่เกี่ยวข้อง: 2Fundamental data analysis
Failing to convert standard prefixed physical units (such as mm, ms, MeV, or u) into SI units before applying core equations.
วิธีหลีกเลี่ยง: Perform conversion steps at the very beginning of your calculation. Note down explicitly that 1 mm = 10^-3 m, 1 ms = 10^-3 s, and 1 u = 1.661 * 10^-27 kg.
3mediumคะแนนที่เกี่ยวข้อง: 2Space, time and motion
Resolving vector components with incorrect trigonometric functions (interchanging sine and cosine).
วิธีหลีกเลี่ยง: Trace out the vector triangle and use SOH CAH TOA explicitly. If resolving tension or velocity, verify whether the angle is relative to the horizontal or vertical axis.
4mediumคะแนนที่เกี่ยวข้อง: 3Matter: hot or cold
Attempting to explain enzyme-catalyzed digestive reactions using qualitative biological descriptions rather than thermodynamic Boltzmann distribution models.
วิธีหลีกเลี่ยง: Describe the enzyme action purely in terms of lowering the activation energy barrier, which increases the Boltzmann factor, representing a higher proportion of particles having energy >= activation energy.
5highคะแนนที่เกี่ยวข้อง: 2Fundamental data analysis
Forgetting to set the calculator to Radian mode during diffraction grating or SHM calculations, or leaving it in Radian mode when resolving structural forces.
วิธีหลีกเลี่ยง: Develop a habit of checking the screen indicator (D vs R) before every exam segment. Use Degrees for force resolution and diffraction angle; use Radians for SHM equations and phase angles.
6mediumคะแนนที่เกี่ยวข้อง: 1Out into space
Omitting the negative sign in orbital gravitational potential energy calculations, leading to physical contradictions regarding system boundedness.
วิธีหลีกเลี่ยง: Use \(E_p = -\frac{GMm}{r}\). Retain the negative sign and add it directly to positive kinetic energy to establish a negative total orbital energy for bound satellites.
7highคะแนนที่เกี่ยวข้อง: 3Ionising radiation and risk
Confusing the radioactive nuclei ratio left (N/N0) with the fraction that has decayed when evaluating elapsed decay times.
วิธีหลีกเลี่ยง: Read the text carefully. If one third of the original nuclei have decayed, then two thirds remain. Use \(N/N_0 = 2/3\) in the exponential decay equation, not \(1/3\).
