Letter scales and printing
Standard scale: A at 90%, B at 80%, C at 70%, D at 60%, F below 60%. Plus/minus uses the boundaries listed above the chart. These are selectable examples, not a rule for every school.
Print uses the browser print dialog and repeats the table heading on later pages. Half points create two rows per question plus the full-score row.
How to use it
- Set the total number of equally weighted questions.
- Choose whole or half points and a letter scale.
- Use the chart while marking, or print it.

Frequently asked questions
How are percentages calculated?
Subtract points wrong from total points, divide by the total and multiply by 100. Each question is worth one point in this chart.
Are the letter grades universal?
No. Choose standard or plus/minus boundaries and check them against your school. Letters use the same one-decimal percentage shown in the table.
