The LSU grade-point table
Grade-point values are per credit hour. GPA = Σ(grade points × credits) ÷ Σ(graded credits), excluding the non-GPA symbols below.
| Letter | Grade points | Notes |
|---|---|---|
| A+ | 4.3 | One-decimal scale — not 4.33 |
| A | 4.0 | Distinguished mastery |
| A− | 3.7 | |
| B+ | 3.3 | Good mastery |
| B | 3.0 | |
| B− | 2.7 | |
| C+ | 2.3 | Acceptable mastery |
| C | 2.0 | |
| C− | 1.7 | |
| D+ | 1.3 | Minimally acceptable |
| D | 1.0 | |
| D− | 0.7 | |
| F | 0.0 | Failure |
P, W, I, NC are not used in computing the official GPA and carry no quality points.
Repeated courses
LSU: when a course is repeated, only the most recent grade counts in the GPA. All attempts stay on the transcript. A C− or better generally cannot be repeated for credit without permission; D+ or lower may be retaken; a third attempt needs dean approval.
Worked example
Worked example. A+ (3 credits) + C− (3 credits) = (4.3 × 3) + (1.7 × 3) = 12.9 + 5.1 = 18.0 quality points ÷ 6 credits = 3.00 GPA (displayed as 3.000). The calculator starts with exactly these two courses.
Assumptions on this page
- All credits are GPA-bearing letter-graded credits. Excluded symbols (P, W, I, NC) are left out by the calculator.
- No repeats in the main table. Repeated courses use the repeat widget below, which applies LSU’s most-recent-counts rule.
- Display: LSU GPAs are specified to three decimals with rounding (3.95550 → 3.956).
Common mistakes
- Writing 4.33 for LSU A+. LSU’s catalog says 4.3. The one-decimal scale is the whole point of this page.
- Using the superseded repeat text. Older LSU text said all instances count in the GPA. The current catalog says only the most recent grade counts.
- Mixing campuses. This page is LSU A&M (Baton Rouge) only. Other LSU System campuses publish different scales.
- Applying a percent scale. LSU’s catalog publishes letter-to-quality-point values only — no percent bands.
- Truncating the GPA. LSU rounds to three decimals; it does not truncate like UF.
