Just fill in your courses
Enter each course's credits and grade and your GPA is computed automatically as a credit-weighted average — the same way your transcript is calculated. Course names are optional; add or remove rows to match this term's schedule.
4.5 and 4.3 scales
Choose the 4.5 or 4.3 maximum used by most Korean universities. A+ maps to 4.5 (or 4.3), A to 4.0, B+ to 3.5 (3.3), and switching the scale recomputes instantly.
Simulate your target
GPA drives scholarships, exchange programs and grad-school applications. Enter expected grades to see whether you reach a target, or change one course to see how the average shifts.
Frequently asked questions
How is GPA calculated?
It is a credit-weighted average: sum of (grade points × credits) divided by total credits, so higher-credit courses count more.
Which scale should I choose?
Match your transcript. Most Korean universities use a 4.5 maximum; some use 4.3.
Do I include pass/fail courses?
No. Pass courses are usually excluded, so remove them or set credits to 0.
Are my grades stored?
No. Everything is computed in your browser; inputs are never sent or saved.
