Final Grade Calculator – This calculator determines what score you need on your final exam to achieve your desired overall course grade based on your current grade and the weight of the final exam.
What is a Final Grade Calculator?
A Final Grade Calculator helps students estimate what score they need on their final exam to achieve a desired overall course grade.
How Does It Work?
To use a final grade calculator, you’ll usually need 3 pieces of information:
- Current Grade – Your average so far based on assignments, quizzes, projects, etc.
- Final Exam Weight – How much the final exam counts toward your total grade (e.g., 20%, 30%).
- Desired Overall Grade – The grade you want to achieve for the course.
Formula
To find out what you need on your final exam, use this formula:
Required Final Grade = (Desired Grade – (100 – Final Weight) × Current Grade) / Final Weight
Solved Example:
Let’s say:
- Your current grade is 75%
- The final exam is worth 30% of your grade
- You want at least an 80% overall
Put into the Formula:
Required Final Grade = (80 – (100 – 30) × 75) / 30 = 91.67%
Conclusion: To get 80% in the course, you need to score at least 91.67% on your final exam.
