Here is a text dictated to students for keyboard practice:
And here is a text typed by a student from the dictation:
The built-in global Needleman–Wunsch alignment algorithm finds student errors:
Calculate a percentage grade by dividing the number of errors by one quarter of the total number of text characters:
Assign letter grades from percentage grades:
Combine the letter grade and corrected text into a framed presentation:
