Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| Grade before final | Numeric value. Unit: %. Zero or positive. Maximum: 100. | 75 |
| Final exam weight | Numeric value. Unit: %. Minimum: 0.000001. Maximum: 100. | 30 |
| Target course grade | Numeric value. Unit: %. Zero or positive. Maximum: 100. | 80 |
Result for these sample inputs
91.6666667 %
A result above 100% requires extra credit or a different target; a negative result means the target is already secured under this model.
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.

The method, explained
Required exam grade = [target − current × (1 − final weight/100)]/(final weight/100).
Using grade before final = 75 %, final exam weight = 30 %, target course grade = 80 %, the result is 91.6666667 %. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
Check the grading or scheduling rules used by your institution. The stated mathematical convention may differ from its policy.
