Test Day Checklist
- First pass: answer every question you know. Bookmark the rest. Every exam lets you return to bookmarked questions.

- Pace: 150 minutes for 50 questions, which is about 3 minutes per question.
- Last step: answer anything still blank. A blank can't earn a point.
Study Tips
On an open-book exam, the winners aren't the smartest people in the room — they're the fastest at finding answers. Buy the required book, practice with it open, and tab and highlight each section the first time a question sends you there. Learn the index and table of contents until you can land on any topic in seconds. That speed is what separates a pass from a fail.
On an open-book exam, work through every question once: answer the ones you know and skip the ones you don't. Then go back to the ones you flagged. You can bookmark questions for later review, just like on our exams — and don't sink too much time into any single question. The clock is still running.
Give yourself at least three to six weeks. Use your exam's candidate bulletin as your roadmap for what's tested, and spend your time on finding-it-fast skills over rote memorization. In practice, aim for three clean passes at 80% or higher — setting your practice bar above the real cut score gives you a comfortable margin on test day.
Practicing against a ticking clock is the best way to beat exam-clock anxiety. Use these timed tests to build your pacing, so you learn to move steadily and never burn too long on a single question. By test day, the format feels routine.
