How it works
The current grade represents all non-final work combined. Enter the final weight as a percentage from greater than 0 through 100.
Required final = (target − current × (1 − weight)) ÷ weight
Worked example
With an 80% current grade, a 90% target, and a 50%-weighted final, the needed score is 100%.
