Before you start

1. The countdown starts when you press "Start exam" and does not stop, not even if you reload the page.
2. You can move back and forth freely, and jump to any question from the question navigator.
3. Flag questions for review and come back to them before finishing.
4. 8 questions require TWO answers; the stem says so and both must be correct to score the point.
5. Unanswered questions are scored as incorrect. There is no penalty for guessing.
6. When you finish you get your score, the breakdown by domain, and a review of every question with its rationale.
