CGPA Calculator for South Korea
Calculate your GPA using South Korea's 4.5 or 4.3 grading system. Credit-weighted as used by SNU, Korea University, Yonsei, KAIST, POSTECH and other universities. Supports relative grading and percentile (Baekbunyul).
Universities in South Korea use a GPA system on a 4.5 scale (most common) or 4.3 scale (e.g. Yonsei, KAIST, Ewha, Sogang). GPA is credit-weighted; credits are called "Credits" (학점). Pass mark is typically 60% or grade C; GPA is shown to two decimal places.
4.5 scale: Most national and private universities (e.g. SNU, Korea University). 4.3 scale: Prestigious international-facing institutions.
Relative Grading (상대평가): Most courses use a fixed distribution (e.g. A: top 30–35%, B: next 35–40%, C and below: remaining). Absolute Grading (절대평가): Small classes, practical arts, or Pass/Fail (P/F) courses. Transcripts often include a 100-point percentile (Baekbunyul, 백분율), used for GKS and major employers.
- Grades: Letter grades (A+, A0, B+, B0, C+, C0, D+, D0, F) — convert to points using your university's scale.
- Weighted sum: Σ(Grade points × Credits).
- GPA: GPA = Σ(Grade points × Credits) ÷ Σ(Credits attempted). P/F and S/U grades grant credits but are excluded from the GPA denominator.
- Retakes (재수강): Usually only for C+ or lower; retaken courses are often capped at A0 (4.0) or B+ (3.5). Old grade is replaced by "R" and removed from GPA but remains on transcript.

GPA = 39.0 ÷ 12 = 3.25 (out of 4.5)
| Course | Credits | Grade | Points | Credit × Points |

| Capstone Project | 5 | B0 | 3.0 | 15.0 |
| Total GPA credits / points | - | - | 48.0 ÷ 14 | |
Total grade points = 12.0 + 9.9 + 11.1 + 15.0 = 48.0 • GPA credits = 14 (Physics Lab excluded)
Semester GPA = 48.0 ÷ 14 = 3.43 / 4.3
Cumulative GPA (CGPA): Standard for graduation.
Term GPA: Average for a specific semester (often shown).
Major GPA: Only core and elective courses within the department.
Converted GPA: 4.3 or 4.0 equivalents for international use.
Academic Warning (Haksa-gyeonggo): Typically if semester GPA < 1.75 or 2.00; three warnings can lead to expulsion.
Honors (U-su): Summa Cum Laude often requires CGPA ≥ 4.0 (4.3 scale) or ≥ 4.3 (4.5 scale). Early graduation possible with GPA ≥ 4.0 for 6–7 semesters.

Korean GPAs are converted by scale normalization (e.g. 4.5 → 4.0: GPA_4.0 = (Korean GPA ÷ Max scale) × 4.0). For the Global Korea Scholarship (GKS), the NIIED Official Conversion Table is often used; if your transcript shows a 100-point score, that is the primary reference. Receiving institutions may request official conversion tables; credential evaluation (e.g. WES) may be required and can treat Korea's strict relative grading differently.
