🧠 30-SECOND FINAL MEMORY
Before you start exam, remember:
✔ Risk = PoF × CoF
✔ Inspection reduces PoF only
✔ CoF is fixed
✔ RBI is dynamic
✔ High consequence = high priority
✔ Always verify, never assume
🎯 FINAL EXAM EDGE
If stuck between two answers:
👉 Choose the one that:
✔ Reassesses risk
✔ Uses data
✔ Is safer
✔ Follows procedure
