Examiner Tips

Expert advice for maximising your marks

💡During the practical assessment, narrate your actions to demonstrate underpinning knowledge, e.g., state why you check electrode alignment before pressing.
💡In written tasks, structure responses around the Plan-Do-Check-Act cycle to show systematic problem-solving approach.
💡When discussing quality issues, always link the observation to potential downstream effects on final cell performance or safety.
💡For technical calculations, show all working and clearly state units, as partial marks are often awarded for correct method even if final answer is flawed.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing the sequence of mixing and coating steps in electrode fabrication, leading to incorrect process flow.
Neglecting to account for environmental conditions (e.g., dew point) when opening dry room interlocks, risking moisture contamination.
Misinterpreting tolerance limits on coating thickness as advisory rather than mandatory, resulting in non-conforming product.
Failing to properly ground equipment before handling flammable electrolyte, increasing electrostatic discharge risk.
