Compare GPA, percentage, letter grade, and attendance policy differences across school and country systems without assuming an official conversion.
Many US schools use 4.0, 4.3, or weighted 5.0-style scales, while Korean universities may use 4.3, 4.5, percentage, or letter-grade systems depending on the institution.
The same letter grade can mean different grade points across schools. Treat any GPA estimate as a planning reference unless your school publishes the exact conversion rule.
A percentage score is often continuous, while a letter grade usually groups ranges into A, B, C, D, or pass/fail outcomes.
When a syllabus lists category weights in percentages but the transcript shows letters or grade points, calculate the course estimate first and then compare it with the official scale.
Attendance rules can be based on total classes, seat time, labs, excused absences, tardies, or a minimum percentage such as 75%, 80%, or 90%.
Use attendance calculators to understand the direction of risk, then verify the exact absence policy in the syllabus or student handbook.
Enter the scale and weights from your own syllabus instead of copying a generic country table. Recalculate after any new grade, absence, deadline, or policy update.
For official transcripts, scholarships, admissions, graduation, or visa-related decisions, use the method required by the school or organization receiving the record.
