How Is Your Grade Calculated?
Your final grade is a weighted average. This means assignments worth more percentage count more toward your final grade.
Formula:
Final Grade = (Score 1 × Weight 1) + (Score 2 × Weight 2) + … divided by total weight
Example:
| Assignment | Your Score | Weight |
|---|---|---|
| Midterm Exam | 78% | 30% |
| Final Exam | 85% | 40% |
| Homework | 90% | 30% |
Final Grade = (78×30) + (85×40) + (90×30) ÷ 100 = 84.4% → Letter Grade: B
Grade Scale – What Do the Letters Mean?
| Percentage | Letter Grade | GPA Points |
|---|---|---|
| 90% – 100% | A | 4.0 |
| 80% – 89% | B | 3.0 |
| 70% – 79% | C | 2.0 |
| 60% – 69% | D | 1.0 |
| Below 60% | F | 0.0 |
