❓ FAQ

How do weighted grades work?

Each category has a weight (percentage of your total grade). Your score in each category is multiplied by its weight. For example, if Homework is 20% and you scored 95%, that contributes 19 points to your final grade.

What if my weights don't add up to 100%?

The calculator will warn you. For accurate results, weights should total exactly 100%.
