How GPA is calculated (weighted by credits)
Your GPA is a credit-weighted average of your grade points. Courses worth more credits count more toward your average. The formula is:
GPA = Σ(grade points × credits) ÷ Σ(credits)
On the common 4.0 letter scale, each grade maps to a grade-point value like this:
| Letter | Grade points | Letter | Grade points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A- | 3.7 | C | 2.0 |
| B+ | 3.3 | C- | 1.7 |
| B | 3.0 | D+ | 1.3 |
| B- | 2.7 | D | 1.0 |
| F | 0.0 |
For example, an A (4.0) over 3 credits and a B (3.0) over 3 credits gives
(4.0×3 + 3.0×3) ÷ 6 = 21 ÷ 6 = 3.50 over 6 credits. Rows with blank or zero
credits are ignored, so you can leave extra rows empty without affecting the result.
