Most courses split your grade into categories: homework 20%, quizzes 20%, tests 40%, final 20%. Enter yours. The calculator tracks your current grade live and tells you exactly where you stand. Add or remove categories freely. No signup.
Match what is on your syllabus: homework, quizzes, tests, final.
Leave categories empty if the work has not happened yet.

See which categories need the most improvement.
Add as many as your syllabus requires.
Shows current average even if not all scores are entered.
Weights that do not sum to 100 are handled automatically.
Even with 5 categories and 20 scores, the layout stays clean on 375px.
Weighted average: each category's percentage score is multiplied by its weight, and the results are summed. Categories without scores are excluded from the total weight.
Example: Homework (20%, avg 92%), Tests (40%, avg 86%), Quizzes (20%, avg 81%), Final (20%, empty).
Weighted sum = 92×0.20 + 86×0.40 + 81×0.20 = 18.4 + 34.4 + 16.2 = 69.0
Active weight = 80%. Overall = 69.0/0.80 = 86.3%
