GPAWorld country hub
GPAWorld covers 11 universities in South Korea. Between them they use 2 different grading scales, the most common being the 4.30 GPA scale at 7 of them. They also round the cumulative average in 2 different ways. That is why this site keeps one grading configuration per university instead of one per country — a single "South Korea GPA formula" would be wrong for most students who used it.

Looking at the South Korea configurations side by side: 2 publish the percentage range behind each letter, which lets you work backwards from a mark to a grade; repeated courses are handled 3 different ways across the group. Each university's own page spells out which of these apply to you.

No. The 11 South Korea universities covered here use 2 different grading scales between them, so the same grades can produce very different GPAs. Pick your university from the list on this page.
Open your university's page from the list above. Enter your current CGPA and completed credit hours, then add this semester's courses with their credit hours and grades. The grade options come from that university's own table, and the result is rounded using its own rule — so the number matches how your registrar calculates it.
No — this group alone uses 2 different rounding rules for the cumulative average: rounded to 2 dp, rounded up to 2 dp. Truncating instead of rounding can be the difference between sitting just above or just below a scholarship threshold, so it is worth checking your own university's rule.
Quite possibly — coverage is being expanded steadily, and each university is only added once its grading policy has been read from an official source and encoded. Send us the university name and a link to its published grading scale and we will add it.
If you want to check the arithmetic by hand rather than trust a calculator, these walkthroughs cover the method that sits underneath every university page on this site.
