I wanted to create an auto-grader. There are many types of students who can be applied this application.
Some are high-achieving High School students, some are Undergraduate students, and some are Graduate students. 
I created a parent (base) Class that can be extended to provide functionality for various kinds of students. 
I assumed that there will be name of the file containing a student’s essay (the student's’ ID number.txt) 
Application grade the essay, by listing all the misspelled.

Writing an essay is hard. 
If I had a nickel for every misspeled word in this essay I would have exactly one nickel.

Rough winds do shake the darling buds of May,
And summer's leese hath all too short a date
