Every online test grader we checked uses this formula: divide the number of right answers by the number of questions on the test. Wikipedia’s Academic grading in the United States provides the plus-minus and 10-point tables we use. You can find each cut-off on the methodology page. If your school uses its own scale, it takes priority, and you can change every cut-off.

Testing

Each sample calculation on the site relies on the same code as the calculator, so a changed outcome makes the build fail.

Mistakes

When an answer looks wrong, email the numbers you typed to contact@calculatorforgrading.org. After checking it, we correct the site if the error was ours.
