Two genuinely different paper structures
Pearson Edexcel IAL Physics is unit-based, sat as separate modular papers across AS and A2 content including two dedicated practical-skills units; CAIE structures Physics around multiple-choice, AS-level and A-level structured-question papers, plus a planning, analysis and evaluation paper. Confirm your own board before assuming either pattern applies to your revision plan.
Practical and data-analysis skills are examined directly
Both boards test practical skills through written questions — apparatus choice, identifying sources of error, processing data including uncertainty, and evaluating experimental design — rather than only through a hands-on practical exam. Treat this as a distinct revision topic with content to learn, not something covered once in a lesson and forgotten.
Calculations — full working for method marks
Multi-step numerical questions carry method marks available even when arithmetic goes wrong, provided your working and units are clearly shown. Keep units consistent throughout rather than converting partway through a calculation, and sanity-check your final answer's order of magnitude.
Explain questions need a full reasoning chain
- Build a complete chain of physical reasoning, not just a correct final statement.
- Show every step of a calculation, including the equation before substituting values.
- Apply concepts to the specific scenario given, not in the abstract.
Common content traps
- Sign errors in vector-based mechanics and field calculations.
- Confusing similar concepts across topics, particularly in electromagnetism and modern physics.
- Incomplete explanations that state a conclusion without the reasoning chain the mark scheme rewards.
