Frequently Asked Questions
How is the required final exam score calculated?
The formula is: Required Score = (Target Grade - Current Grade × (1 - Final Weight)) / Final Weight. This is derived from the weighted average formula used to calculate your final grade.
What if the required score is over 100%?
If the calculator shows a score over 100%, it means your target grade is not achievable even with a perfect score on the final. Consider adjusting your target grade to something more realistic.
What if the required score is negative?
A negative required score means you've already secured your target grade! Even scoring 0% on the final would still give you your desired grade.
How do I find my final exam weight?
Check your course syllabus or ask your instructor. Common final exam weights are 20%, 25%, 30%, or 40% of the total grade.
Does this account for extra credit?
This calculator uses standard weighted averages. If your class offers extra credit, your actual required score may be lower than calculated.
