Examiner Tips

Expert advice for maximising your marks

💡Always align your practical work with the provided standard operating procedure (SOP) to demonstrate compliance and attention to detail.
💡Immediately record any anomalies or unexpected results and suggest possible reasons, as this shows strong evaluative and problem-solving skills.
💡In a practical assessment, narrate your actions to the assessor if permitted, explaining why you are performing each step, to evidence your understanding.
💡Before submission, meticulously review your lab notebook to ensure all entries are dated, signed, and free from informal language or unexplained shorthand.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing accuracy with precision, often using the terms interchangeably in practical reports.
Failing to properly label samples or reagents, leading to potential cross-contamination or misidentification.
Overlooking the recording of environmental conditions (e.g., temperature, humidity) that may affect experimental results.
Neglecting to document any deviations from the standard method or unexpected observations during the procedure.
