Piecewise linear curve

To assign letter grades to numeric grades, the department of mathematics use the standard break values as follows.

A range: a grade of 90 or more
B range: a grade of 80 or more
C range: a grade of 70 or more
D range: a grade of 60 or more

If the Professor has adjusted your scores using a piecewise linear curve, you can use this tool to find your score

Enter the values for the curved A,B,C,D break points in that order (four comma-separated numbers). For example, if the adjusted ranges are A: 85, B: 70, C: 55, D: 40, enter '85,70,55,40'
