| Letter Grade | GPA Points | Typical % Range | Quality Points (3-credit) |
|---|---|---|---|
| A+ | 4.0 (some schools 4.3) | 97–100% | 12.0 |
| A | 4.0 | 93–96% | 12.0 |
| A− | 3.7 | 90–92% | 11.1 |
| B+ | 3.3 | 87–89% | 9.9 |
| B | 3.0 | 83–86% | 9.0 |
| B− | 2.7 | 80–82% | 8.1 |
| C+ | 2.3 | 77–79% | 6.9 |
| C | 2.0 | 73–76% | 6.0 |
| C− | 1.7 | 70–72% | 5.1 |
| D+ | 1.3 | 67–69% | 3.9 |
| D | 1.0 | 63–66% | 3.0 |
| D− | 0.7 | 60–62% | 2.1 |
| F | 0.0 | Below 60% | 0.0 |
Note: percentage cutoffs vary by institution and professor. Some schools use 90/80/70/60 as letter grade breakpoints; others use 93/83/73/63. Always check your course syllabus for the exact scale used in that class.
Your GPA is calculated from quality points, not letter grades directly. Quality points = GPA value × credit hours. A B (3.0) in a 3-credit course earns 9.0 quality points. An A (4.0) in a 4-credit course earns 16.0 quality points. Your cumulative GPA = total quality points ÷ total credit hours attempted.
This is why a 4-credit course affects your GPA more than a 3-credit course. An A in a 4-credit course adds 16 quality points; an A in a 3-credit course adds 12. A C in a 4-credit course drops your GPA more than a C in a 3-credit course. High-credit courses in your schedule deserve proportionally more of your study time.
| GPA | Equivalent Grade | Significance |
|---|---|---|
| 4.0 | All A's | Perfect GPA; summa cum laude at most schools |
| 3.7+ | Mostly A's with occasional A− | Magna cum laude at most schools; highly competitive for graduate programs |
| 3.5+ | Mostly A's with some B+'s | Dean's list at most schools; competitive for most graduate programs |
| 3.0+ | B average | Most common scholarship GPA minimum; minimum for many graduate programs |
| 2.5+ | B− to C+ average | Minimum for some graduate programs and state scholarship renewals |
| 2.0+ | C average | Minimum to remain in good academic standing; below this risks academic probation |
The GPA impact of each grade depends on how many credits you have already completed. Early in college (under 45 credits), each grade has a large effect — an A in a 3-credit course when you have 15 credits completed adds 0.13 GPA points. Later (90+ credits), the same A adds only 0.02 GPA points. This is why front-loading strong grades early in college is the highest-leverage GPA strategy available to most students.
