Free Grade Calculator (+ Guide)

A grade calculator works out your grade in a class from each part, weighted by its share.

This free one also shows what you need on the final for every letter.

Multiply each score by its share of the grade, add them up, and divide by the shares you've done.

The calculator does it from your scores.

The final you need = (the grade you want − your grade so far × the share already done) ÷ the final's share.

Add the final's share in the calculator to see it for every letter.

Then that grade is out of reach with the final alone.

Ask your teacher about extra credit, or aim for the next letter.

Some schools use other cutoffs.
