Grades
Admin Settings › Grades Settings: for each level (Primary, O-Level, A-Level, Nursery) enter the lower and upper mark of every grade and its remark, e.g. O-Level A = 75–100 Excellent, B = 65–74 Very good, C = 45–64 Good, D = 30–44 Satisfactory, F = 0–29 Fail. Submit and check the preview.
Points
Admin Settings › Point Settings: points per grade (NECTA style: A=1, B=2, C=3, D=4, F=5 for O-Level; A=1 … S=6, F=7 for A-Level).
Divisions
Admin Settings › Divisions Settings: the total-points range of each division, computed from the best seven subjects (O-Level) or the best three principal subjects (A-Level): e.g. Div I = 7–17, II = 18–21, III = 22–25, IV = 26–33, 0 = 34–35.
