One diagnostic brain, three assessment personalities
What each pathway covers, and where it is thin
Every competence below is counted from the material actually authored — practice questions, drills, checklists, scenario rubrics, mocks and templates. The shared core carries the method. Each region adds the assessment flavour its examiners mark on: East Africa — observed method plus evidence; United States — code-aware judgment plus calculation accuracy; South Africa — practical task quality plus documentation discipline.
