Final Exam Grade Formula

If you want to understand the math behind the result, here's the formula:

Final Exam Grade = (Desired Grade − (1 − Exam Weight) × Current Grade) / Exam Weight

Example:

  • Current grade: 70%
  • Desired grade: 80%
  • Final exam weight: 50%

Calculation: Final Exam Grade = (80% − (1 − 0.50) × 70%) / 0.50 = (80% − 35%) / 0.50 = 45% / 0.50 = 90%

So you'd need a 90% on your final exam to finish the course with an 80%.
