How this calculator works
For tests scored by right and wrong answers, your percentage is the points scored divided by the maximum points. With one point per question and no penalty, that is simply correct answers ÷ total questions.
Score = correct × points per question − wrong × penalty; Percentage = score ÷ (questions × points per question) × 100
Example: 40 questions, 6 wrong, no negative marking: 34 ÷ 40 = 85%. With 0.25 negative marking the score is 34 − 1.5 = 32.5, or 81.25%.
Unanswered questions score zero and are not penalised. Teachers can open the grading chart to see the percentage for every possible number of wrong answers.
