Weighted grade calculator
Weighted grade calculator
A course mark built from the components your syllabus marks — each one scored as a percentage and carrying its own weight.
How this is calculated
Weighted average = sum of ( score x weight ) / sum of weights. The weights do not have to add to 100 for the mean to be valid, but a course whose components total 100 is the usual case, so the page reports the weight it actually summed and says when that total is not 100.
- The page does not know which components your syllabus counts, whether a dropped lowest score applies, or how the school rounds the final mark. It computes the weighted mean of exactly the rows you enter.
- A component scored zero is not a missing component. If the paper was marked and the score was zero, enter zero with its weight; leave the score empty only for a component that has not been marked.
A course mark is a weighted mean, and the weights are the part that goes wrong. This page multiplies each component score by the share the syllabus gives it and divides by the weights you actually entered.
Why the weights are shown, not assumed
Every component is entered twice: once as the percentage earned in it, once as the share of the course it carries. The arithmetic is the sum of score times weight, divided by the sum of weights. It does not need the weights to add to 100 to be correct, but a course whose components do add to 100 is the usual case, so the page reports the total it summed and says when that total is something else.
A component scored zero is a marked component, not a missing one. Enter the zero with its weight; leave the score empty only where the paper has not yet been marked. A dropped lowest score, a best-of rule or a moderation step changes the course mark, and the page does not model any of them. The figures it uses are the rows you enter.
Questions readers ask
What if my weights add to more than 100?
The page still returns the weighted mean of what you entered: each score times its weight, divided by the total weight. The verdict says the weights do not add to 100 so you can check whether a component was counted twice. It does not quietly renormalise, because a total over 100 usually means a row is wrong rather than that the syllabus uses a different scale.
Does the final course mark get rounded?
No. The percentage is printed to two decimals and the arithmetic keeps the unrounded figure. Whether a school rounds a course mark, and to how many places, is its own rule; apply it after the calculation rather than before.
