To determine your GPA on a 4.0 scale, you need to convert your grades to their corresponding values on the scale. The 4.0 scale is the most commonly used GPA scale, where an A or A+ is worth 4.0, a B is worth 3.0, a C is worth 2.0, a D is worth 1.0, and an F is worth 0.0. Pluses are an additional one-third of a point, while minuses are the subtraction of one-third of a point. For example, an A- is a 3.7, and a B+ is a 3.3. To calculate your overall GPA, you need to average the scores of all your classes.
If you have your grades in letter format, you can use the following chart to determine what your grade is on a 4.0 scale:
| Letter Grade | Percent Grade | 4.0 Scale |
|---|---|---|
| A+ | 97-100 | 4.0 |
| A | 93-96 | 4.0 |
| A- | 90-92 | 3.7 |
| B+ | 87-89 | 3.3 |
| B | 83-86 | 3.0 |
| B- | 80-82 | 2.7 |
| C+ | 77-79 | 2.3 |
| C | 73-76 | 2.0 |
| C- | 70-72 | 1.7 |
| D+ | 67-69 | 1.3 |
| D | 65-66 | 1.0 |
| E/F | Below 65 | 0.0 |
Keep in mind that your high school may use a different grading scale, and your GPA listed on your high school transcript might not be what is used by college admissions, since there is a lot of variation in high school grading scales, additional points added for honors, advanced, AP, IB courses. For admissions, many colleges will recalculate student GPA so there is consistency/equity across applicants based on institutional standards and may not include all high school coursework or weights.
