F = 75 - 2q
- F = Final Score
- 75 = initial or raw score
- q = number of questions that are incorrect or left blank
The formula deducts 2 points for each incorrect or blank question. If you get 4 questions wrong, for example, your score will be:
F = 75 - 2·4 = 75 - 8 = 67
If you get no questions wrong, your score is:
F = 75 - 2·0 = 75 - 0 = 75
That is why 75 is the initial raw score.
