Formula Used
Gross Points = Correct Answers × Points per Correct Answer
Penalty Points = Incorrect Answers × Penalty per Incorrect Answer
Net Score = Gross Points − Penalty Points + Bonus Points
Maximum Score = Total Questions × Points per Correct Answer
Percentage Score = (Net Score ÷ Maximum Score) × 100
Attempt Rate = (Attempted Questions ÷ Total Questions) × 100
Accuracy Rate = (Correct Answers ÷ Attempted Questions) × 100
The calculator then compares the percentage score with your grade thresholds and passing percentage to assign a grade and pass or fail status.
