  • Build a recognized mental arithmetic skill profile that stays with you

IMAR · International Mental Arithmetic Rating

One rating. A student's entire mental-arithmetic journey.

IMAR is Num Champ's rating system — it starts with a first assessment and updates automatically as a student practices, tests, and competes, so progress is always visible.

  • Establish an initial skill rating as your starting point
  • Monitor improvement through continued practice and participation
  • Compare your current ability against defined competency expectations

  • Stay motivated with a recognized mental arithmetic skill profile

IMAR is a Num Champ concept for describing skill progression — it is not affiliated with, or a copy of, any existing rating system. Detailed rating formulas and scoring calculations will not be published.
