Grade Calculator
Most courses combine an already-completed portion of the grade with a final exam still to come — this blends the two together using the course's own weighting to project the final overall percentage.

80.1 %
Completed portion contributes 54.6%
How the grade calculator works
Completed portion's contribution = current score × (weight already completed ÷ 100).
Remaining portion's contribution = expected final exam score × ((100 − weight completed) ÷ 100).
Final projected grade = completed contribution + remaining contribution.
Worked example: 78% current score, 70% of the grade already completed, expecting 85% on the final
- Completed contribution = 78 × 70 ÷ 100 = 54.6.
- Remaining contribution (30% of the grade, expecting 85%) = 85 × 30 ÷ 100 = 25.5.
- Final projected grade = 54.6 + 25.5 = 80.1%.
Common mistakes to avoid
Confusing 'weight completed' with a raw percentage of the total course score
Weight completed refers to how much of the grade's total weighting has already been determined (e.g. assignments and midterms worth 70% of the final grade combined), not the score received on those components — those are two separate numbers this calculator needs distinctly.
Assuming the current score already reflects the whole course rather than just the completed portion
The 'current score' entered should represent performance on just the completed weighted components specifically, not a blended guess at the whole course — mixing this up double-counts or under-counts part of the calculation.
Frequently asked questions
How is 'weight completed' different from 'current score'?
Current score is how well you've done (a percentage) on the parts of the course already graded; weight completed is what fraction of the total course grade those parts represent — a student could have a high current score but a low weight-completed figure if most of the course grade is still ahead.
What does it mean if the projected final grade seems impossible to achieve?
If even a 100% on the remaining weighted portion wouldn't be enough to reach a desired target, that specific target isn't mathematically achievable given the current standing — this is exactly what the Final Exam Mark Calculator is built to check directly.
Can I use this partway through a course to see if I'm on track?
Yes — entering your actual current performance and a realistic (rather than best-case) expected final score gives a genuinely useful projection of where the course grade is heading.
How is this different from the Weighted Grade Calculator?
This tool specifically splits a course into 'already completed' and 'still to come' portions; the Weighted Grade Calculator combines any list of individual assignment scores and weights directly, without that completed/remaining split.
