The best way to reach GradeLogic is by email: [email protected]

Useful to include

• Which calculator you were using
• The numbers you entered and the result you saw
• What you expected instead, if you think something is wrong

Messages are read and answered by the site owner, usually within a few working days. We can't advise on your school's specific grading policies — your teacher or registrar is the right person for that.

Please don't send personal documents such as transcripts. They aren't needed to check a calculation.
