Weights and scores answer different questions
A 90% homework score does not mean homework contributes 90 points to the final course grade. The category contribution is the score multiplied by its weight.
Make category weights total 100%
The tool flags incomplete or excessive weighting so the current grade is not presented as more precise than the syllabus supports.
Use scenarios for remaining work
Adjust category scores to explore realistic outcomes before a final exam or project.
Follow the syllabus
Dropped assignments, curved grades and special rules can require a custom calculation beyond a simple weighted average.
