Understanding Grading Scale and Grading Chart
A grading scale refers to the standardized range used to assign a letter grade (A, B, C, D, F) based on percentages. For example:
A: 90–100%
B: 80–89%
C: 70–79%
D: 60–69%
F: Below 60%
A grading chart shows the breakdown of possible scores and their corresponding percentage grades for a specific total number of questions. It’s especially useful in class settings when multiple students have different incorrect answers.
