Calculations

The Weighted Average Mark (WAM) = the Weighted Sum (WS) / Sum of Weights (SW)

where:

• Each course has its own fixed Course Weight and Stage Weight.
  

• WS =
  the sum [over all included courses] of (
      the product of (
          the Mark for the course's first attempt
          the Course Weight of the course
          the Stage Weight of the course
      )
  )
  

• SW =
  the sum [over all included courses] of (
      the product of (
          the Course Weight of the course
          the Stage Weight of the course
      )
  )
