Semester Grade Calculator
Calculate completed weight, current contribution, projected course grade, final-exam score required for a target, and target margin. The custom gradebook visual shows how much of the 100-point course result is already carried and what the final can add.

How to use Semester Grade Calculator
- Confirm that the current average already represents all completed weighted work.
- Enter the final exam's exact course weight.
- Compare projected and required scores with the syllabus, remaining assignments, rounding policy, and grade caps.
Calculator guide
Understanding Semester Grade Calculator
A semester grade is a weighted sum, not a simple average of the current grade and final exam. The completed-work contribution must be preserved before the final's remaining weight is applied.
Calculation method
How the calculation works
Weight the current completed-work average by the portion of the course already completed, add the final-exam contribution, and solve the same equation for the score required to reach the target grade. Multiply the current average by completed weight, add final score times final weight, and rearrange that equation to solve the required final score.
Final-exam plan
Interpret the required score before setting a study target
The number is useful only when the gradebook structure is correct.
Worked situations
Practical examples
- A final worth 35% leaves 65% completed coursework.
- An 82% current average contributes 53.3 course points before the final.
- Reaching an 85% target then requires enough final-exam points to close the remaining gap.
Better inputs
Useful tips
- Use category weights from the syllabus rather than assignment counts.
- Include ungraded remaining work separately if the final is not the only remaining component.
- Check whether extra credit, dropped scores, curves, or letter-grade rounding apply.
Before relying on the result
Limitations and common mistakes
- The model assumes the final exam is the only remaining graded component.
- Gradebook weighting, category caps, dropped items, missing work, curves, extra credit, and institutional rounding are excluded.
- A required score above 100% signals infeasibility under the entered structure.
Reference
Key terms
- Completed weight
- Course percentage already represented by the current average.
- Contribution
- Weighted course points supplied by one component.
- Projected grade
- Weighted result using the expected final score.
- Required final
- Final-exam score solving the target equation.
Important note
Calculated directly from the entered values using the displayed formula and rounding settings.
Frequently asked questions
Why is the current grade not averaged 50/50 with the final?
Each component must be multiplied by its actual course weight.
What does a required score over 100% mean?
The target is not reachable under the entered weights without other grade changes.
Can several remaining assignments be entered?
Not directly; combine them into a weighted remaining scenario or use a fuller gradebook.
Does the calculator round letter grades?
No. Apply the official course policy separately.
