Overall Verdict
The 2024 AQA GCSE Chemistry Foundation Tier papers (Paper 1F and Paper 2F) were well-structured and aligned perfectly with the specification, offering a fair test for candidates of all abilities. The paper combined straightforward recall tasks with practical-based application, making a solid grade highly achievable for well-prepared students who mastered the core practicals (RPAs).
Where the Marks Were Won & Lost
High scoring was concentrated in the early parts of questions focusing on atomic models, hydrocarbon structures, and basic separation techniques. However, significant marks were lost in the following areas:
- Titration & Quantitative conversions: Many students struggled to convert volume units from \( \text{cm}^3 \) to \( \text{dm}^3 \) before calculating concentration, or omitted the final rounding to three significant figures.
- Rate of Reaction explanations: When asked to explain the effect of concentration, many candidates failed to use the precise phrase "frequency of collisions" or "collisions per second", instead stating simply that there were "more collisions".
- Experimental Planning (Level of Response): The 6-mark design questions (e.g., investigating chemical cells and potable water treatment processes) suffered from a lack of logical sequencing and missing control variables.
Examiner Pitfalls & Misconceptions
A common pitfall was drawing the start line in chromatography in ink rather than pencil, which remains a classic error. Additionally, in reaction profile drawings, students frequently drew the activation energy arrow incorrectly (not starting from the reactants level) or mislabelled the reactants and products.
Preparation Strategy for Next Series
To maximize scores in the upcoming series, students must focus on practicing conversion calculations (mass to concentration) and memorizing exact definitions of key chemical terms. Regularly reviewing the steps and reasons for each Required Practical Activity (RPA) will secure high-tariff marks in the experimental design questions.
