Examiner Tips

Expert advice for maximising your marks

💡Always link practical actions to underlying principles; for example, explain why a specific piece of equipment is chosen for a measurement task.
💡Practice writing up laboratory reports using a structured format, ensuring all sections (aim, method, results, conclusion) are complete.
💡Familiarise yourself with common laboratory equipment and their limitations to answer application-based questions effectively.
💡When tackling questions on quality control, reference specific techniques like repeat measurements, calibration curves, and control samples.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing precision with accuracy when using measuring instruments.
Failing to calibrate equipment or zero balances before use.
Recording data in non-standard units or omitting units entirely.
Overlooking PPE requirements or failing to conduct a risk assessment.
Relying on memory rather than following written SOPs, leading to procedural errors.
