CGPA is a common way to measure a student’s overall academic performance. It's calculated by taking the norm of grade points earned in all subjects across several semesters.
Different universities may use different grading scales, such as 4.0, 5.0, or 10.0. In India, most colleges and universities follow the 10-point grading system.
