この計算機の使い方
- Choose the grading scale. Most US schools give A+ the same 4.0 as an A; some give 4.33.
- For each course, choose the letter grade and enter its credit hours. Set credits to 0 for unused rows.
- To find your cumulative GPA, enter your current GPA and the total credits it is based on.
計算式
GPA is a credit-weighted average of grade points. Each course contributes its grade points multiplied by its credits (quality points).
GPA = Σ(grade points × credits) / Σ credits
Cumulative GPA = (old GPA × old credits + new quality points) / (old credits + new credits)
Example
- A (4.0) × 3 credits = 12; B+ (3.3) × 4 = 13.2; A− (3.7) × 3 = 11.1; B (3.0) × 3 = 9; A × 1 = 4.
- Total quality points = 49.3 over 14 credits.
- GPA = 49.3 / 14 ≈ 3.52.
よくある質問
What is a good GPA?
Above 3.0 is generally considered good and above 3.5 very good, but expectations depend on the school, programme and goal (for example, graduate admissions).
Do pass/fail courses count?
Usually not. Pass/fail courses earn credits but no grade points, so leave them out of the GPA calculation.
Is weighted high-school GPA supported?
This calculator uses the unweighted 4.0 scale. Some high schools add 0.5 or 1.0 points for honors and AP courses; check your school's policy.
