Difficulty Verdict

The 2025 HKDSE Physics examination is classified as moderately difficult (4 stars). While the mathematical computations are standard, the paper requires a high level of conceptual accuracy, particularly in distinguishing between related physical quantities (e.g., gravitational force vs. reaction force in orbit, and magnetic flux vs. induced e.m.f.).

Where the Marks Are

Marks are heavily concentrated in Wave Motion (stationary waves, light reflection/refraction, and lens diagrams) and Electricity and Magnetism, which together account for more than a third of the total score. Students who mastered ray-tracing techniques and wave equation manipulations secured a substantial base of marks. In Paper 1B, the multi-step calculations in Q11 (power plant and transmission) and Q10 (stationary waves) served as key differentiators for high-achievers.
