Fast grading without a paper wheel

The chart shows every possible score for the selected test length. The highlighted row tracks the current number wrong.

test percentage = (questions − wrong) ÷ questions × 100

The displayed letter uses a common US scale: A begins at 93%, A− at 90%, B+ at 87%, and F is below 60%. This is only a default. Change the letter grade according to the teacher's or school's published scale.
