A grading scale is a system used to evaluate and communicate a student's academic performance. It typically assigns letter grades, such as A, B, C, D, and F, with corresponding grade point values. For example, an A might represent excellent performance, while an F indicates failure. The scale helps educators assess student understanding and progress. Different institutions may use variations of grading scales, such as a 4.0 scale or percentage-based systems. In a 4.0 scale, an A is often worth 4 points, while a C is worth 2 points. These scales provide a standardized way to compare student performance across different classes and schools.
