Examiner Tips

Expert advice for maximising your marks

💡In the practical assessment, narrate your actions clearly to the assessor, explaining why you choose each test or tool—this demonstrates underpinning knowledge.
💡Always prioritise safety and ESD protocols visibly during tasks; assessors will deduct marks for missed steps, even if the repair is successful.
💡Prepare a portfolio with multiple repair case studies, including before-and-after photos, diagnostic logs, and customer sign-offs to showcase consistent competency.

Common Mistakes

Pitfalls to avoid in your exam answers

Failing to back up or secure customer data before commencing repair, leading to potential data loss or breach of GDPR.
Misdiagnosing power-related faults as battery failures without first testing charging circuits and connectors with a multimeter.
Overlooking manufacturer-specific service manuals or schematics, resulting in damage to proprietary fixtures such as ribbon cables and ZIF connectors.
