Estimates, not official grades

Every result produced by TeacherCalc is an estimate calculated from the numbers you enter and the standard published grading scales described on each page. TeacherCalc is not affiliated with any school, school district, university, examination board or government education department, and no result on this site is an official grade, transcript entry or admission decision.

Why your official grade may differ

Institutions apply their own policies on top of raw arithmetic: rounding at grade boundaries, dropping lowest scores, curving, moderation between markers, participation components, late penalties and institution-specific scale tables. Any of these can move an official grade above or below the estimate a calculator produces from scores alone.

Conversions between countries

Conversions between grading systems, including UK to US GPA and Australian WAM to GPA, use widely published approximate equivalencies and are provided for guidance. Universities and credential evaluation services apply their own conversions to complete transcripts and their determination governs any application.

No professional advice
