Calculate what grade you need on your final exam to achieve your desired course grade.
Here's a step-by-step guide on how to use a Final Grade Calculator:
Enter your current grade before the final exam in the "Current Grade (%)" field, the final grade you want to achieve in the "Desired Grade (%)" field, and how much the final exam is worth in the "Final Exam Weight (%)" field. Then click "Calculate Required Grade" to see the result.
For Example:
Current grade is 70% (or C-).
Final exam weight is 50%.
Required grade is 80% (or B-).
The final exam grade is equal to the required grade, minus 100% minus the final exam weight (wfinal) times the current grade (g), divided by the final exam weight (w):
Final exam grade = (80% - (100% - 50%) * 70%) / 50% = 86%
So Final exam grade =
= required grade - (100% - wfinal)×current grade wfinal = 80% - (100% - 50%)×70% 50% = 90%
So the final exam grade should be 90% (or A-).
