How does the European 1–10 scale work?

Below the pass threshold the grade maps linearly from 1 (minimum) to 6 (sufficient). Above the threshold it maps from 6 to 10. The default threshold is 60%.

Can I change the pass threshold?

Yes — on the European scale the pass threshold is fully customisable. Letter-grade scales use fixed, standard thresholds.

Do I need an account to use this?

No. The calculator is completely free and needs no account. Scales you want to keep live in GapFiller, next to your lessons.

What is the difference between this and the test grade calculator?

They share the same engine. This page is designed for teachers converting marks across scales; the test grade calculator uses student-facing language.

How to convert marks to grades

Converting raw marks to a meaningful grade depends on the grading scale your school uses. This calculator supports five common systems — European (1–10), UK A-Level, UK GCSE 9–1, UK University (First through Fail), and US letter grades (A–F) — so you get an accurate result regardless of where you teach or study.

For numeric scales like the European 1–10, you can set a custom pass threshold that controls where the 'sufficient' grade (6) falls. For letter-grade scales the thresholds are built in.

Quick example

A student scores 28 out of 40. That is 70%. On the US scale the grade is a C. On the European scale with a 60% threshold it maps to a 7.5 out of 10. On UK A-Level it is a B.

The same raw score produces different labels depending on the system — use this tool to compare them instantly.
