Frequently asked questions
- How does a weighted grade work?
- Each category is multiplied by its weight fraction and summed. For example, a 90% score on homework worth 30% contributes 27 points to your final grade.
- What if my weights don't add up to 100%?
- The calculator normalises automatically — it divides by the total weight you enter, so partial category entry still gives a meaningful average.
