"AB" is not a standard letter grade defined in the typical GPA conversion scale. Grade point average (GPA) systems commonly assign specific percentage ranges and 4.0 scale values to letter grades such as A, A-, B+, and B.
Understanding these standard conversions is crucial for evaluating academic performance. The table below outlines how common letter grades map to percentage ranges and their equivalents on a 4.0 GPA scale:
GPA Conversion Scale
| Letter Grade | Percent Grade | 4.0 Scale |
|---|---|---|
| A | 93-96 | 4.0 |
| A- | 90-92 | 3.7 |
| B+ | 87-89 | 3.3 |
| B | 83-86 | 3.0 |
This table helps illustrate the defined grades and their corresponding values in a standard grading system.
