Examiner's Verdict
The October/November 2025 paper set was balanced but demanding. Mechanics and electrical circuits followed well-established assessment structures, but candidates encountered significant difficulty in descriptive explanations of particle behavior and astronomical speed calculations.
Key Mark Allocations
High-scoring opportunities lay in core formulaic calculations, specifically in finding kinetic energy, power transfers, and wave frequencies. Conversely, marks were heavily lost on descriptive questions requiring precise vocabulary, such as explaining how gas particles exert pressure on container walls and detailing conduction in metallic vs. non-metallic rods.
Examiner Pitfalls
A persistent source of lost marks was the omission of units or using incorrect capitalization (e.g., lowercase w instead of uppercase W). In practical and theory ray-tracing, failing to draw clean, thin normal lines at exactly 90 degrees compromised accuracy. Additionally, many candidates struggled to scale graphs correctly or state definitions verbatim as outlined in the syllabus.
Strategic Guidance & Predictions
For future preparation, students must practice converting non-SI units (like converting mA to A or kW to W) prior to multi-stage calculations. Topics such as radioactive decay equations, electromagnetic induction, and momentum conservation were under-tested in the structured papers, making them highly probable focus areas for the upcoming examination cycle.
