How it is calculated
Average = sum(grade × weight) ÷ sum(weights). Weights are normalised; a non-100 total triggers a notice.
A worked example
Grades 7, 7, 7 and 9 with equal weights yield an average of 7.500.
Before using your result
A zero weight excludes that component. Total weight must exceed zero. Check your actual assessment criteria before interpreting the result.
How to enter reliable inputs
Pre-filled values are examples only. Replace every input and check its unit before calculating: a unit error can change the result substantially. Use decimals where needed and ensure you have not left a zero where a real value is required.
When comparing scenarios, change one input at a time and save both summaries. This shows which variable explains the difference. Downloaded summaries contain your inputs and results, but do not replace professional or official documentation.
