How GPA Is Calculated
Every GPA is the same idea: convert each grade to points, weight each class (equally in high school, by credit hours in college), and average. On the standard scale an A is 4.0, a B is 3.0, a C is 2.0, and plus/minus grades fall in between. Weighted GPAs add a rigor bump — typically +0.5 for Honors and +1.0 for AP, IB, or Dual Enrollment — before averaging.
| Unweighted | Weighted | |
|---|---|---|
| Scale | 0 – 4.0 | 0 – 5.0 (typically) |
| A in AP Calculus | 4.0 | 5.0 |
| A in regular English | 4.0 | 4.0 |
| What it measures | Raw grades | Grades + course rigor |
| Who uses it | Colleges comparing applicants | High schools for class rank |
