One practice exam per certification is your Leaderboard Exam — the exact same exam for every candidate worldwide. You can take it during any attempt, whenever you choose. It's designed as a fun way to see who's genuinely at the top, with ties common and everyone sharing the top score listed together, alphabetically.
Your score is reported as your IRT theta — a measure of your ability across the full spectrum, rather than a raw percentage.
What Makes This the Leaderboard Exam?
Unlike ordinary practice exams, the Leaderboard Exam is identical for every candidate worldwide. Everyone competes on the same questions, making the leaderboard a meaningful and fun comparison of performance.
You don't have to take it at a particular time. Take it during any attempt, whenever you choose, and your result will be included in the global leaderboard.
Every candidate takes the exact same Leaderboard Exam, creating a common benchmark for everyone around the world.
See how your performance compares with candidates worldwide and find out who is genuinely at the top.
Candidates with the same top score share the same rank. Everyone tied for the top position is listed together, alphabetically.
Your result is reported as IRT theta, a measure of your estimated ability across the full spectrum — not simply the percentage of questions you answered correctly.
The Leaderboard Exam is a shared global benchmark. The exact same exam is presented to every candidate worldwide, so your performance can be compared directly with everyone else who has taken it.
You can take the exam during any attempt and whenever you choose. There is no need to coordinate your attempt with other candidates.
The leaderboard uses your IRT theta score rather than a raw percentage. Because theta measures ability on a psychometric scale, it is designed to represent your position across the full ability spectrum.
