What is the formula to calculate a quiz score?

To calculate the score of an exam that features penalty deductions, a standard formula is used to prevent random guessing from inflating the final grade.

Score = [Correct - (Incorrect / K)] * (Max Score / Total Questions)

* K represents the number of answer options minus 1 (if there are 4 options, every 3 wrong answers deduce one correct answer).
