Question

where are the errors the  pseudocode debugging exercise

// This application reads student typing test data
// including number of errors on the test, and the number
// of words typed per minute. Grades are assigned based
// on the following table:
//           Errors       
// Speed       0       1    2 or more
// 0–30        C       D       F
// 31–50       C       C       F       
// 51–80       B       C       D
// 81–100      A       B       C
// 101 and up  A       A       B
