- Open book. Have your reference books tabbed and on the desk before you start — the lookup under time pressure is the skill being tested.
- You need 70% to pass. Every question counts equally.
- The clock runs continuously and never pauses. When time expires, the exam submits and scores itself automatically.
- Mark any question for review. The Navigator shows every question’s status and lets you jump to any question.
- There is no penalty for guessing — an unanswered question is simply scored wrong. Never leave one blank.
