Combining different assessment types into one grade
Most courses don't weight every assignment equally — a final exam might count for 40% of the grade while weekly quizzes count for 10% combined. This calculator handles that weighted combination directly, rather than requiring manual calculation for each category.
Weighted average = Σ(score × weight) ÷ Σ(weight)
Dividing by the total weight (rather than assuming it's always exactly 100) means the calculation still produces a sensible result even if your weights don't sum perfectly to 100% — useful if you're working with partial information or estimating before all category weights are finalized.
Using this to plan ahead
Beyond calculating a current grade, this tool is useful for forward planning: enter your completed work as-is, then add a placeholder entry for an upcoming exam or project with different hypothetical scores to see what result each scenario would produce — a quick way to understand exactly how much a remaining assessment matters to your final grade.
