Teacher Chart Generation Example
For a 30-question classroom test, the table generates:
- 0 Wrong: 30 / 30 = 100% (Grade A+).
- 1 Wrong: 29 / 30 = 96.7% (Grade A).
- 2 Wrong: 28 / 30 = 93.3% (Grade A).
- 3 Wrong: 27 / 30 = 90.0% (Grade A-).
- 4 Wrong: 26 / 30 = 86.7% (Grade B).
- Teachers can grade entire stacks of tests by referencing this single chart.
