Grading Made Simple

Teachers spend way too much time on grade calculations. These formulas handle the repetitive work: converting scores to letters, calculating clean averages, and tracking attendance.

Standard US Grading Scale

60-69 D 1.0
Below 60 F 0.0

Why IFS Beats Nested IFs

The old way of writing grade formulas used nested IFs that were impossible to read. IFS lets you write conditions in order, making it easy to adjust your grading scale.

💡 Pro tip: When calculating class averages, always exclude zeros (students who were absent). Otherwise, a few no-shows will tank your class average unfairly.
