The Grade Point Average (GPA) Scale is a system used to measure academic performance in schools and colleges. It typically ranges from 0.0 to 4.0, where each letter grade corresponds to a specific point value. For example, an A is usually worth 4.0 points, a B is worth 3.0 points, a C is worth 2.0 points, a D is worth 1.0 point, and an F is worth 0.0 points. To calculate a student's GPA, the total grade points earned are divided by the total number of credit hours taken. This provides a standardized way to evaluate and compare academic achievements across different institutions and programs.
