GPAWorld country hub
GPAWorld covers 2 universities in Thailand. All 2 of them publish the 4.00 GPA scale, but that shared label does not make them interchangeable: their grade tables, pass marks and repeat rules are set institution by institution. That is why this site keeps one grading configuration per university instead of one per country — a single "Thailand GPA formula" would be wrong for most students who used it.

All on one published scale, each with its own grade table and rounding. Every listing links to a calculator preloaded with that university's own rules.

This is the clearest argument against using one national formula. Take a student who earns their university's second-best grade in four courses— identical academic performance, on paper — and run it through each institution's own rules:
Assumption University
Second-best grade: A- (3.75 points)
3.75
Semester GPA
Thammasat University
Second-best grade: B+ (3.5 points)
3.50
Semester GPA
Same effort, same relative result, different number — because the scales, point values and rounding rules are set by each university rather than by Thailand. A calculator that ignores this gives most students the wrong figure.
Looking at the Thailand configurations side by side: repeated courses are handled 2 different ways across the group. Each university's own page spells out which of these apply to you.
| University | Scale | Top grade | Lowest pass | CGPA rounding | Repeats |
|---|---|---|---|---|---|
| Assumption University | 4.00 GPA scale | A (4.0) | D (1.0) | Rounded to 2 dp | Manual review |
| Thammasat University | 4.00 GPA scale | A (4.0) | D (1.0) | Rounded to 2 dp | All attempts count |
No. The 2 Thailand universities covered here share the 4.00 GPA scale, but they set their own grade tables, pass marks, rounding and repeat rules. Use your own university's page rather than a shared formula.
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.
Because the point values differ. Four courses at the second-best grade give 3.75 at Assumption University (A- = 3.75 points) but 3.50 at Thammasat University (B+ = 3.5 points). Identical performance, different numbers.
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.
