A-Level Chemistry topics and skills a tutor can diagnose
Across the main specifications, the challenge is not just remembering content. A learner may understand an idea but lose marks when applying it to an unfamiliar context, translating words into a calculation, explaining a mechanism, interpreting spectra, evaluating a practical method or linking several topics under time pressure. Calculations deserve explicit attention: AQA and Pearson Edexcel each state that at least 20% of their overall assessment uses mathematical skills at Level 2 or above.
- Does the learner understand the idea but lose marks in calculations?
- Can they draw a mechanism but not explain it precisely?
- Can they connect spectra or analytical data to structure?
- Can they evaluate a practical method and discuss uncertainty?
- Can they combine topics in synoptic, timed questions?
- Quantitative Chemistry
- Amounts of substance, concentration, pH, graphs, units and multi-stage calculations.
- Physical Chemistry
- Energetics, kinetics, equilibria, acids and bases.
- Inorganic Chemistry
- Periodicity, redox, electrochemistry and transition metals.
- Organic Chemistry
- Reactions, mechanisms, synthesis and functional-group reasoning.
- Analytical techniques
- Spectra, data interpretation and structure determination as required by the specification.
- Practical and data skills
- Variables, apparatus choices, graphs, uncertainty, evaluation and observations.
- Synoptic application
- Combining topics and communicating reasoning in unfamiliar contexts.
