What is this tool?

Many courses grade by category weights that should sum to 100%. Overall ≈ Σ(score × weight) / Σ(weights). If your weights don’t sum to 100, this tool still computes using the weights you entered and warns you.

How to use it

  1. List each grading category with its weight and your score.
  2. Adjust rows to match your syllabus.
  3. Read overall % (and letter estimate) and fix weights if they don’t sum to 100.
