How the calculation works
A weighted grade combines each score multiplied by its share of the final grade.
Example
If exams count 60% at 80% and homework counts 40% at 95%, the weighted grade is 86%.
Things to keep in mind
- Enter scores and weights carefully and confirm the weights match the course policy.
- Curves, extra credit, missing assignments and dropped scores can change a final grade.
- The result is an estimate based on the inputs and assumptions provided.
- Check applicable terms and official guidance before making financial, employment or academic decisions.
