How the final mark calculator works
Last updated 10 November 2026
Most courses combine tests, assignments and an exam into one final mark. Each part counts for a share of the total, called its weight.
How it works
- Marks banked = mark × weight ÷ 100, added up across assessments.
- The weight still to come is 100% minus the weights you entered.
- Final mark with a given mark in the rest = marks banked + that mark × the remaining weight ÷ 100.
Worked example
With the starting figures:
- The example marks bank 26.9 out of 100.
- 60% of the final mark is still to come.
- A mark of 50% in the rest would give a final mark of 56.9%.
How to read your result
The headline shows the marks you have banked so far, out of 100. This is not your average. Each mark is scaled by its weight, so a high mark on a small test adds less than a modest mark on a large assignment.
The rows below show how much of the final mark is already marked and how much is still to come. In the worked example, 60% is still to come. The extra rows show what your final mark would be for a few different results in the rest.
Weights explained
A weight is the share of the final mark an assessment is worth. Weights should add up to 100% across the whole course. If you leave the exam out, the weights you enter add up to less than 100%, and the calculator treats the difference as the part still to come.
If the weights you type add up to more than 100%, the calculator shows an error, because the weights cannot be correct.
Common mistakes
- Entering a mark out of a different total. Enter it as a percentage, so a test out of fifty with a score of forty is eighty.
- Typing the weight of a whole group instead of each item. Add each assessment as its own row, or enter the group as one row with its combined weight.
- Using an average of several tests when the course counts the best ones only. Check the course guide for how tests are combined.
- Forgetting a sub-minimum. Some courses require a minimum mark in the exam, however good the rest is.
What this does not cover
The calculator does not apply any rounding, supplementary exam rules, dropped marks or minimum requirements that your institution uses. It also does not know whether a mark has been moderated. Treat the result as a guide and check the official rules in your course guide.

What if I have not written the exam yet? Leave the exam out. The weight still to come shows what is left, and the extra rows show what the final mark would be for a few possible exam results.
What if I want to know the exam mark I need? The required exam mark calculator works out the mark you need for a target.
Can I enter group marks? Add each assessment as its own row, with its own mark and weight.
Things to watch
- Use the weights from your course guide.
- Some courses need a minimum in the exam to pass, whatever the final mark.
- Rounding rules vary.
