Grading like a Scantron

Input the Key to the test, then input the student answers to the test.

Compare and grade the results using C=Correct and W=Wrong

3 arrays are all you need!

Very much like this

Key A B C D A B C D A B C C A B C D A B C D

Answers A A C A A B C D A B C D A B B D A B C D

C/W C W C W C C C C C C C W C C W C C C C C

Percentage Correct = 80%
