Calculate weighted GPA from course credits and grades using configurable grade scales.
GPA = Σ(课程绩点 × 学分) ÷ Σ学分。百分制按内置换算表转为绩点(如 90+→4.0、60+→1.0、不及格 0);切换院校等级制时换算口径随之变化。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Common GPA scales | 4.0 scale: A=4.0, B=3.0, C=2.0, D=1.0, F=0; 90+ often mapped to 4.0 | Common US higher-education convention |
| Weighted GPA | GPA = Σ(grade points × credits) ÷ Σcredits | Standard registrar algorithm |
| PKU refined scale | PKU algorithm refines bands (85–89→3.7, 90–94→3.9 etc.); differs from WES evaluation | Peking University GPA algorithm |
| WES evaluation | WES converts Chinese percentages conservatively (80–84 often B/3.0); rely on the evaluation | WES official conversion notes |
