Le guide ci-dessous n'est pas encore disponible en français et s'affiche en anglais. Le calculateur lui-même est entièrement traduit.
Comment utiliser ce calculateur
- Enter the score (%) and weight (%) for each category.
- Set unused rows' weight to 0.
- If the weights don't add up to 100% (for example, mid-semester), the result shows your current grade based on completed categories.
Formule
Each category's score is multiplied by its weight, and the sum is divided by the total weight.
Weighted grade = Σ(score × weight) / Σ weight
Example
- Homework 92% (20%), quizzes 85% (30%), exams 78% (40%), project 100% (10%).
- = (18.4 + 25.5 + 31.2 + 10) / 100 = 85.1%.
