I've designed a tree diagram to depict the grading classifications used in this course. This diagram includes the five distinct grades: (A) Excellent, (B) Very Good, (C) Good, (D) Pass, and (F) Fail. In this system, grades ranging from A (90-100) signify excellent performance. The B range (80-89) reflects very good performance, the C range (70-79) corresponds to good performance, and the D range (60-69) indicates a passing grade. Any score below 59 is categorized as failing, which is represented by an F in the grading system. Within each passing grade there is a high, mid-range, and low category represented by plus, solid, and minus.
