## Final grade calculator

Find what grade you need on the final exam:

### Example

Current grade is 70% (or C-).

Final exam weight is 50%.

Required grade is 80% (or B-).

#### Calculation

The final exam grade is equal to 100% times the required grade, minus 100% minus the final exam weight (w) times the current grade (g), divided by the final exam weight (w):

*Final exam grade* =

= ( 100%×*required grade* - (100% - *w*)×*current grade* ) / *w*

= ( 100%×80% - (100% - 50%)×70% ) / 50% = 90%

So the final exam grade should be 90% (or A-).
