In the US letter grading system, 90 to 100 percent is typically an A, 80 to 89 a B, 70 to 79 a C, 60 to 69 a D, and 0 to 59 an F. There is no letter E. Cutoffs can vary, so check your own school's scale.
In the US letter grading system, your percentage on assignments is converted to a letter from A to F. Typical bands run from 90 to 100 percent for an A down to 0 to 59 percent for an F.
Percentage to Letter Grade
| Percentage | Grade | Description |
|---|---|---|
| 90 to 100% | A | Excellent |
| 80 to 89% | B | Great |
| 70 to 79% | C | Improve |
| 60 to 69% | D | Close fail |
| 0 to 59% | F | Fail |
Other Points
- The letter grading system does not include the letter E.
- The US also uses a numerical system on a 4.0 scale, where percentages are converted to grade points.
- Exact cutoffs can differ by school, so check your own institution's scale.
My Advice
Use this table as a general guide only. When you convert your own marks for an application, follow the grading scale the university or evaluator specifies.
