How the grading scale works

Most US schools grade on a 10-point scale: 90% and up is an A, 80–89% a B, 70–79% a C, 60–69% a D and anything below 60% an F. A D is usually the lowest passing grade.

Many high schools and colleges add plus and minus grades to tell the top and bottom of each range apart. They matter for GPA: a B+ is worth 3.3 points, a B− only 2.7. There is no universal plus/minus table, but the one above is the most common; some schools give an A+ 4.3 instead of 4.0.

Grading a test

Score = (questions − wrong) ÷ questions × 100

With 25 questions each one is worth 4%, so 3 wrong is 88% — a B. Rather than working it out for every paper, open the chart for your test length above, or use the Easy Grader, which also handles half points and custom scales.

Turning grades into GPA

Each letter maps to GPA points on the 4.0 scale (the GPA column above). To average your classes, use the GPA calculator; for what a GPA means, see the GPA chart.

Frequently asked questions

What is the standard grading scale?

In most US schools: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69% and F = below 60%. On the 4.0 GPA scale those letters are worth 4, 3, 2, 1 and 0 points.

What is a plus/minus grading scale?

It splits each letter into three: the top of the range gets a plus and the bottom a minus. A common version is A 93–96%, A− 90–92%, B+ 87–89%, B 83–86%, B− 80–82% and so on, each step worth 0.3 or 0.4 GPA points.

Is 60% passing?

On the standard scale 60–69% is a D, which is usually a passing grade in high school and college. Some schools and programs need a C (70%) or higher for a class to count.

What is a 7-point grading scale?

An older scale some districts still use, where each letter covers 7 points instead of 10: A 93–100, B 85–92, C 77–84, D 70–76 and F below 70. You can grade on it with the custom scale in the Easy Grader.

How do I make a grading scale for a test?

Divide 100 by the number of questions to get the value of each question, then take that much off per wrong answer. Or open the chart for your test length on this page — it lists the score and letter for every number wrong, ready to print.
