How we measure readiness
What the readiness percentage on your report actually means, and how the diagnostic arrives at it.
Adaptive questioning
Each answer adjusts what comes next — a correct answer raises the difficulty, a miss lowers it — so a ~20 minute session finds your actual level instead of testing everything.
Per-skill mastery, not one score
Every sub-skill in the exam blueprint is scored on its own 0–100% mastery scale, so two students with the same overall percentage can have completely different gaps.
Ranked by point cost
The report orders weak skills by how much they are likely costing you, not alphabetically or by how badly you did — so the first thing to fix is the highest-leverage one.
Retaken, not fixed once
Mastery is tracked as a series over time, not a single snapshot — retaking the check re-scores every skill so you can see a fix hold.
What we do not claim
A readiness score is an estimate from your answers, not a guaranteed test-day result — real exams add time pressure, format and nerves the check cannot fully model. We do not promise a specific score, and any peer ranking shown is only as reliable as the number of other students who have sat that exact paper.
Common questions
What does the readiness percentage on my report mean?
It is your estimated mastery across the skills the diagnostic tested — not a raw score. Each sub-skill is scored independently on a 0–100% mastery scale, and the overall readiness number summarises those sub-skill scores.
How does the adaptive diagnostic work?
The check adjusts difficulty question by question: a correct answer raises the difficulty, a miss lowers it. That lets a ~20 minute session find your actual level instead of spending time on questions far above or below it.
Why does my report show four gaps instead of one score?
One overall number hides where the points are actually being lost. The report breaks performance down by sub-skill and ranks the weakest ones by how much they are costing you, so the next study session has a clear target.
Can I retake the check to see if a gap closed?
Yes — retaking the check re-scores every sub-skill, so you can watch a specific gap move as you work on it rather than relying on a single test date.
