Frequently asked questions
What if my weights don't add up to 100%?
That's fine — the calculator normalizes by the total weight you've entered, so partial or over-100% totals still produce a correct proportional result.
Can I use this to find what I need on a final exam?
Yes — add your existing categories as usual, then add a "Final exam" category with its weight and try different score values until the overall grade hits your target.
