Mapping from /50 to /6 scale:

  • 0/50 --> 1/6
  • 20/50 --> 4/6
  • 31/50 --> 5/6
  • 42/50 --> 6/6
In between these 4 levels, the scale is linear, i.e.,
if x is the grade out of 50, and y is the grade out of 6:
  • 0<x<22, y = 3x/20 + 1
  • 22<x<33, y = (x-20) /(31-20) + 4
  • 33<x<45, y = (x-31)/(42-31) + 5
  • x>=45, y = 6
