The ladder
Eight titles. One honest number.
Every full assessment lands you on one of eight rungs. Here is the whole climb, and what actually moves the number.
1
Only full assessments move it.
Gap re-checks never touch the rating, so the number is always earned.
2
Every answer adjusts the difficulty.
Beat questions above your level and the rating climbs fast, Elo style.
3
One attempt per 14 days.
Ratings stay honest because you cannot grind them daily.
