FAQ
Frequently asked questions
Do my weights need to add up to 100?
No — the calculator normalizes automatically, so weights just need to reflect the correct relative proportions.
What should I use as weights?
Your syllabus's stated category weights — e.g. homework 20%, midterm 30%, final 50%.
Do the two lists need to match in length?
Yes, each score needs a corresponding weight in the same position.
How do I find the score I need on a remaining assignment?
