How Final Exam Scores Are Calculated
The formula to determine what score you need on your final exam is:
Final Exam Score Needed = (Desired Grade – (Current Grade × (100% – Final Weight))) / Final Weight
Where:
- Desired Grade is your target overall course percentage
- Current Grade is your percentage before the final
- Final Weight is what percentage of your grade the final exam counts for
