Timed mixed set — 10 questions

Exam-mode: answer under the clock, no feedback until the end. Then a full review with per-question timing.
The drill. 10 fresh scenario questions spanning all five domains, in the exam's "best first step / most effective change" style — none repeat the lesson quizzes or your mock. 15:00 on the clock (≈90s/question — tighter than the real exam on purpose).
