Mapping from /50 to /6 scale:

  • 0/50 --> 1/6
  • 28/50 --> 4/6
  • 40/50 --> 5/6
  • 48/50 --> 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<28, y = 3x/28 + 1
  • 28<x<40, y = (x-28) /(40-28) + 4
  • 35<x<48, y = (x-40)/(48-49) + 5
  • x>=48, y = 6
