GPA 計算式とガイド
GPAを計算するには、各成績を4.0スケールの数値に変換します。この数値に科目の単位数を掛けて「加重評点（Quality Points）」を求めます。すべての加重評点を合計し、それを合計単位数で割ることで算出されます：GPA = 合計加重評点 ÷ 合計単位数。
| Letter Grade | 4.0 Scale Value |
|---|---|
| A+ | 4.0 |
| A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| D- | 0.7 |
| F | 0.0 |
Sample GPA Calculation
Here is a typical single semester GPA calculation breakdown, showing how grade points are weighted by course credits to compute the final average:
| Course | Credits | Grade | Grade Points | Quality Points |
|---|---|---|---|---|
| ENG 101 | 3 | A | 4.0 | 12.0 |
| MATH 121 | 4 | B+ | 3.3 | 13.2 |
| PSY 201 | 3 | A- | 3.7 | 11.1 |
| BIO 110 | 2 | C+ | 2.3 | 4.6 |
| Total | 12 | — | — | 40.9 |
⭐ GPA = 40.9 ÷ 12 = 3.41
GPA Calculation Exceptions
Not every type of class affects your academic GPA in the same way. The table below outlines how special grade types are processed:
| Grade Type | How It Affects GPA |
|---|---|
| Pass/Fail | A Pass (P) gives credit but does not affect GPA. A Fail (F/NP) counts as 0.0 and lowers GPA. |
| Withdrawal (W) | A standard 'W' does not affect GPA. A 'WF' (Withdraw-Fail) may count as an F (0.0) depending on school rules. |
| Incomplete (I) | Not included in GPA until the final grade is submitted. |
| Retaken Courses | Some colleges replace the old grade; others average both attempts. Check your academic catalog. |
| Transfer Credits | Count toward degree progress, but typically do not affect institutional GPA. |
