The Teacher's Gradebook Scratchpad

Class averages, weighted final grades, test percentages, and curved scores: type them the way you would pencil them in a gradebook and read the answers next to each line.

Built for teachers

Weighted Final Grades

Define `homework = 92` and `exam = 78`, then `final grade = homework * 0.3 + exam * 0.7`. Change a weight or a score and the result updates instantly.

Test Percentages

Turn a raw score into a percentage with `score / points possible * 100`, or add a curve with `score + 5%` and see the new mark straight away.

Class Averages

List a column of scores on consecutive lines and use the `average` keyword to get the class mean, or `total` to add up points across an assignment.

One Tab Per Class

With Lifetime, keep every class on its own tab. Rename tabs by period or subject so third period never overwrites the numbers from first.
