If the difference between the grade and the next multiple of 5 is less than 3, round grade up to the next multiple of 5.
If the value of grade is less than 38 , no rounding occurs as the result will still be a failing grade.

round to
grade = 84 (85 – 84 is less than 3)

grade = 29 do not round (result is less than 40)

grade = 57 do not round (60 – 57 is 3 or higher)
