How the Final Grade Calculator Works
Most courses have a weighted grading system. The final exam is usually worth 20–50% of your grade. The rest comes from midterms, homework, quizzes, etc.
Final Exam Score Formula
Required Final Score = [(Desired Grade × 100) − (Current Grade × (100 − Final Weight))] / Final Weight
Example:
- Current Grade: 78%
- Final Weight: 30%
- Desired Grade: 85%
- Required = [(85 × 100) − (78 × 70)] / 30 = 102% (Not possible!)
Try lowering your target or improving current grade.
Real Example: Passing the Class
- Current: 65%
- Final: 40%
- Want: 70% (C)
- Required = [(70 × 100) − (65 × 60)] / 40 = 77.5% on final
