The formula
Percentage = (total marks obtained ÷ total maximum marks) × 100. Note this is not the average of subject percentages unless every subject has the same maximum. Example: 85/100, 78/100, 80/100, 90/100, 92/100 gives 425 ÷ 500 × 100 = 85%.
Worked example
Different maximums
| Maths 45/50 + English 70/100 | 115 ÷ 150 = 76.67% |
| Average of 90% and 70% | 80%, which is wrong here: the true figure is 76.67% |
