Understanding Weighted Grades
What is a Weighted Average?
A weighted average gives different values (weights) to different scores. For example, if exams are worth 60% and homework is worth 40%, a perfect exam score contributes more to your final grade than perfect homework.
Formula
Weighted Average = Σ(Score × Weight) / Σ(Weight)
Where:
- Score = Your grade on each assignment (as a percentage)
- Weight = How much that assignment counts toward your final grade
Example Calculation
| Assignment | Score | Weight |
|---|---|---|
| Midterm | 85% | 30% |
| Homework | 92% | 20% |
| Project | 78% | 20% |
| Final | 88% | 30% |
Weighted Average = (85×30 + 92×20 + 78×20 + 88×30) / (30+20+20+30) = (2550 + 1840 + 1560 + 2640) / 100 = 85.9%
Grade Needed Calculation
Formula
Required Score = (Target Grade - Current Grade × (1 - Final Weight)) / Final Weight
Example
- Current Grade: 75%
- Target Grade: 80%
- Final Exam Weight: 30%
Required Score = (80 - 75 × 0.70) / 0.30 = (80 - 52.5) / 0.30 = 91.67%
Letter Grade Scale
| Letter | Percentage | GPA Points |
|---|---|---|
| A+ | 97-100% | 4.0 |
| A | 93-96% | 4.0 |
| A- | 90-92% | 3.7 |
| B+ | 87-89% | 3.3 |
| B | 83-86% | 3.0 |
| B- | 80-82% | 2.7 |
| C+ | 77-79% | 2.3 |
| C | 73-76% | 2.0 |
| C- | 70-72% | 1.7 |
| D+ | 67-69% | 1.3 |
| D | 63-66% | 1.0 |
| D- | 60-62% | 0.7 |
| F | 0-59% | 0.0 |
Tips for Academic Success

- Prioritize High-Weight Items: Focus more effort on heavily weighted assignments
- Calculate Scenarios: Use the calculator to see how different scenarios affect your grade
- Plan Ahead: Know what you need before the final to reduce stress
- Stay Realistic: If you need 120% on the final, consider other options
