PUTTING IT INTO PRACTICE
Final Exam Grade Needed: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Current grade excluding exam (%) | 70 |
| Final exam weight (%) | 40 |
| Target course grade (%) | 80 |
| Result | 95 % |
- Check the input labels and enter the example values above.
- Apply the relationship: Required exam (%) = (target − current × (1 − exam weight/100))/(exam weight/100).
- The result is 95 %, rounded for display.
How to interpret your result
A result above 100% may be unattainable; a negative result means the target is already met under these weights.
Use the grade scale and credit rules supplied by your institution. A required exam grade above the available maximum signals an unattainable target under the entered assumptions. Repeated-course and extra-credit rules need separate handling.
Frequently asked questions

Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
