The 100-point scale is a grading system commonly used in education to evaluate student performance. In this system, scores range from 0 to 100, with higher scores indicating better performance. For example, a score of 90-100 typically represents an "A," while a score of 60-69 may indicate a "D." This scale allows for a clear distinction between different levels of achievement. It is often used for assignments, tests, and overall course grades, providing a straightforward way for teachers and students to understand academic progress and areas needing improvement.
