🧮 2. How Does a Grade Calculator Work?
The grade calculator computes your grade using a simple formula:
Percentage = (Marks Scored / Total Marks) × 100
Once the percentage is calculated, it determines the corresponding letter grade (A, B, C, D, or F) based on a grading scale -- either simple or detailed.
You can use the Solvezi Grade Calculator to automatically perform these calculations.
