JHU uses a plus/minus 4.0 scale. A+ and A both count as 4.0 — the GPA is never above 4.0.

How JHU GPA Is Calculated
JHU multiplies each grade's quality-point value by the course's credits, sums the quality points, then divides by total credits.
📝 Worked Example
A three-course example using the JHU quality-point scale:
| Course | Credits | Grade | Quality Point | Quality Points |
|---|---|---|---|---|
| Calculus I | 4.0 | A | 4.00 | 4 × 4.00 = 16.00 |
| General Chemistry | 3.0 | B+ | 3.30 | 3 × 3.30 = 9.90 |
| Expository Writing | 3.0 | C− | 1.70 | 3 × 1.70 = 5.10 |
| Total | 10.0 | — | — | 31.00 |

The Conversion Formula
JHU uses a 4.0 scale, so:
Example: If your GPA is 3.5, then Percentage = 3.5 × 25 = 87.50%.

Note: At JHU, A+ and A both equal 4.0 — the GPA cannot exceed 4.0.
| Letter Grade | Quality Points | Definition |
|---|---|---|
| A+ | 4.00 | Excellent |
| A | 4.00 | Excellent |
| A− | 3.70 | Excellent |
| B+ | 3.30 | Good |
| B | 3.00 | Good |
| B− | 2.70 | Good |
| C+ | 2.30 | Satisfactory |
| C | 2.00 | Satisfactory |
| C− | 1.70 | Satisfactory |
| D+ | 1.30 | Passing (minimal) |
| D | 1.00 | Passing (minimal) |
| F | 0.00 | Failure |
📌 Grades Excluded from GPA
The following marks carry no quality points and are not counted in the GPA computation: S (Satisfactory), U (Unsatisfactory), W (Withdrawal), AU (Audit), and I (Incomplete).
Under the S/U option, a grade of C− or above earns Satisfactory credit (S); a grade below C− is recorded as Unsatisfactory (U). Neither affects your GPA. When a course is repeated, the most recent grade replaces the earlier one in the GPA, though both remain on the transcript.
JHU GPA — Frequently Asked Questions
What GPA scale does Johns Hopkins University use?
JHU uses a plus/minus 4.0 quality-point scale: 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, and F = 0.0. Quality points are multiplied by credits to compute the GPA.
Is A+ worth more than 4.0 at JHU?
No. At Johns Hopkins, an A+ carries 4.0 quality points, identical to an A. JHU does not award 4.33 for an A+, so a JHU GPA can never exceed 4.0.
Do S and U grades affect my JHU GPA?
No. Satisfactory (S) and Unsatisfactory (U) grades carry no quality points and are excluded from the GPA computation. Under the S/U option, a grade of C− or above earns an S; below C− is recorded as U.
How do I convert my JHU GPA to a percentage?
Use Percentage = GPA × 25 (equivalent to (GPA ÷ 4.0) × 100). For example, a GPA of 3.5 converts to 87.5%.
What happens to my GPA when I repeat a JHU course?
When a course is repeated, the most recent grade replaces the earlier grade in the GPA calculation. Both attempts remain visible on the transcript, but only the latest counts toward the GPA.
