Formula for Calculating Marks Percentage
The mathematical formula used to calculate exam score percentage is simple and universal:
For example, if a student scores 425 marks out of a total maximum of 500 marks in five subjects:
- Marks Obtained: 425
- Total Maximum Marks: 500
- Calculation: (425 ÷ 500) × 100 = 0.85 × 100 = 85.00%
- Assigned Grade: Grade A (Excellent Performance)
