Exam Tips for Defence Awarding Organisation Vocationally-Related Qualification Design and Technology

Use diagrams to explain system layouts.
Focus on safety implications of each system.
Relate systems to submarine operational scenarios.
Always start by annotating the design brief: underline key performance indicators, highlight constraints, and create a quick checklist of deliverables.
Use a design journal or logbook continuously; a well-maintained record can earn marks even if the final product has flaws.
In technical drawings, double-check alignment with the physical prototype and ensure all critical dimensions are explicitly stated with appropriate tolerances.

Common Mistakes to Avoid

Confusing snort induction with ventilation exhaust.
Overlooking the importance of air purification in confined spaces.
Mixing up fresh water and cooling water systems.
Students often misinterpret the brief by focusing only on explicit requirements and missing implied user needs or environmental constraints.
Producing a single design concept without exploring alternatives, leading to a narrow solution that does not demonstrate creative problem-solving.
