Score needed on final

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%.
