Frequently Asked Questions

What if my weights do not add up to 100%?

The calculator averages over the weights you actually entered, so partial courses still work — it shows the weight total it used so you can check.

Where do I find the weights?

Your course syllabus lists them, usually near the grading section. If only the final weight is known, use the final grade calculator instead.
