Cómo calcular
Grade % = (Points Earned ÷ Total Points) × 100
Grade Percentage is calculated by dividing Total Earned Points by Total Possible Points, then multiplying by 100: Grade % = (Points Earned ÷ Points Possible) × 100. Standard letter grades map to percentage ranges (e.g., 90-100% = A, 80-89% = B, 70-79% = C, 60-69% = D, <60% = F).
* Ejemplo: 45/50 → 90%
