Why Letter Grades Vary
Letter grades are shorthand for performance, but they are not universal. A 75 may be treated differently in the US, UK, Canada, or Australia, and universities may also use pass, merit, distinction, or GPA bands. Use this result as a quick estimate, then confirm the official meaning with your syllabus.
Common mistakes to avoid
- Assuming all schools use the same letter-grade bands.
- Forgetting plus/minus grading.
- Treating a GPA estimate as official.
