How the 4.0 scale works
The 4.0 scale assigns a point value to each letter grade. Your GPA is the average of these points across your courses. Most U.S. schools use this scale, with an A worth 4.0, B worth 3.0, C worth 2.0, D worth 1.0, and F worth 0. Plus and minus grades add or subtract roughly 0.3.
