How to use this tool
Enter the current average excluding the final, the desired grade on the same 0–100 scale, and a final weight strictly between 0 and 100 percent.
Results and examples
With a current 80, a final worth 20% and a target 84, the needed final is 100. A requirement above 100 signals an unreachable target under this weighting model.
Worked example
With a current 80, a final worth 20% and a target 84, the needed final is 100. A requirement above 100 signals an unreachable target under this weighting model.
Limitations
- Extra credit, curves, dropped scores and course rounding rules are not included.
- Negative or over-100 requirements are arithmetic outcomes outside the normal exam range.
