Executive Difficulty Verdict

The 2024 AQA AS Physics series (Papers 1 and 2) balanced standard mathematical derivations with taxing conceptual requirements. While Paper 1 tested core theory with high demands on descriptive accuracy—especially in the nuclear and mechanical modules—Paper 2 required sharp graphical interpolation, error analysis, and the integration of diverse topics like energy storage systems and thin-wedge optical interference. Combined, they form a challenging Grade 4/5 difficulty curve that highly penalized superficial preparation.

Where the Marks Are Won and Lost

A significant portion of marks resided in mathematical setups and graphical readings. Candidates who consistently showed intermediate steps, such as writing down general equations (like \( \Delta E_p = mgh \) or \( E_s = \frac{1}{2} k \Delta L^2 \)) before substitution, secured valuable partial credit. Conversely, key marks were lost in the descriptive questions: failing to mention specific range parameters for the strong nuclear force (repulsive under \( 0.5\text{ fm} \) and attractive up to \( 3\text{ to }4\text{ fm} \)), and omitting to link both Newton's second and third laws when describing changing air resistance.

Examiner Pitfalls & Strategy

  • Uncertainty Arithmetic: In Paper 2, many students struggled to explain why the absolute uncertainty in the trolley displacement was \( \pm 2\text{ mm} \), missing the crucial point that a displacement measurement is a difference between two individual readings, each carrying a \( \pm 1\text{ mm} \) uncertainty.
  • Scale Reading and Units: Non-standard graph scale divisions frequently led to incorrect force and velocity values. Practising on high-resolution grid plots is non-negotiable.
  • Targeted Descriptive Frameworks: For 'Explain' or 'Deduce' questions, structure your answers sequentially. For instance, in wave boundary questions, always explicitly state which parameters (such as frequency or string length) remain constant first.

Prediction for Upcoming Series

With Force, energy and momentum continuing to dominate mark weightings, future papers are highly likely to shift their focus towards 2D projectile mechanics and vector resolution. Additionally, after a highly theoretical quantum section in this series, expect upcoming assessments to feature a high-mark practical-based inquiry into the photoelectric effect or the determination of Planck's constant using LEDs.
