Extended Paper Suite Verdict
The October/November 2024 variant 2 physics suite represents a balanced but highly rigorous assessment of the 0625 syllabus. Paper 22 and Paper 42 demanded not only strong conceptual understanding but also rapid, precise numerical calculations. Key scoring areas are concentrated in the Electricity and Magnetism and Waves units, which carry a significant portion of the total marks.
Where the Marks are Found
The highest concentration of marks is found in Electrical quantities (16 marks) and Physical quantities and measurement techniques (15 marks), primarily driven by Paper 62's core focusing on slide stacks and circuit configurations. Theoretical explanations in thermal transfer also represented a key differentiator, demanding clear vocabulary regarding molecular behaviors.
Common Pitfalls to Avoid
- Tangent Drawing: In Paper 42, calculating instantaneous acceleration required drawing an accurate tangent at \(t = 400\text{ s}\). Many students lost marks due to poorly aligned tangents or arithmetic slips in calculating the gradient.
- Unit Conversions: Calculating orbital speed of Venus in \(\text{m/s}\) required transforming period from days to seconds. This multi-step conversion was a frequent source of errors.
- Precision in Definitions: Vague definitions of physical quantities, such as failing to define weight specifically as a gravitational force, continues to be a common issue.
Strategic Advice
Candidates should focus heavily on step-by-step working. When calculating density or electrical current, stating the primary formula first (e.g., \(\rho = \frac{m}{V}\)) guarantees partial credit even if a final computation goes awry. Additionally, practical planning in Paper 62 must always include independent, dependent, and control variables clearly structured in a results table format.
