Examiner Tips

Expert advice for maximising your marks

💡When being assessed on practical tasks, verbalize your actions as you perform them to demonstrate your understanding and decision-making process.
💡For portfolio-based assessments, ensure all evidence is logically organized and cross-referenced to the relevant learning outcomes and performance criteria.
💡In written assignments, always relate theoretical principles back to specific laboratory examples or case studies to show applied understanding.
💡Before practical exams, practice the step-by-step sequences of common procedures so that they become automatic, reducing the chance of error under observation.

Common Mistakes

Pitfalls to avoid in your exam answers

Learners often fail to zero or tare a balance before weighing, leading to systematic measurement errors.
A frequent mistake is neglecting to label samples clearly and legibly, causing potential mix-ups or invalid results.
Many learners overlook the need to check calibration status of equipment before use, assuming it is always accurate.
In risk assessments, learners commonly confuse hazards and risks, or provide generic control measures rather than specific ones for the task.
