Key examiner messages

Top priorities from the principal examiner before you revise

1

The most lucrative questions were multi-step calculations, which rewarded structured working and unit conversions.

2

For example, in Mechanics and Thermodynamics, many candidates successfully calculated the energy required to heat and melt metals but lost marks on final comparisons.

3

In Working as a Physicist, marks were lost due to poor handling of uncertainties—particularly failing to double the percentage uncertainty of a diameter when squaring it to calculate a cross-sectional area (A=πd24 A = \pi \frac{d^2}{4} A=π4d2​).

Examiner notes & key calculations

  • Algebraic Derivations: Students often struggled to mathematically show that the gradient of a sonometer graph equals T4μ \frac{T}{4\mu} 4μT​. Be meticulous in substituting wave speed into the frequency equation.
  • Precise Terminology: In explanation questions, examiners looked for precise terms. For example, simply saying 'magnetic field changes' was rarely enough; the phrase 'rate of change of magnetic flux linkage' was needed to secure full marks.
  • Graph Skills: Drawing tangents is a perennial weakness. In Paper 1 (Q18biv), the tangent needed a large triangle base (at least 0.06 s 0.06\text{ s} 0.06 s) to ensure accuracy.
