First Of all, we’d write down the scoring and grading system used by the school. The example below is used by Foodtech Building School (FBS).

Score Range (%)	Grade	Score Range (%)		Grade
75 – 100	A1	40 – 44		D2
70 – 74	A2	35 – 39		E1
65 – 69	B1	30 – 34		E2
60 – 64	B2	25 – 29		G1
55 – 59	C1	20 – 24		G2
50 – 54	C2	0 – 19		F
45 – 49	D1	No Entry		NE
		Sick	SS

REM Program to input score and compute grade

        Grade = “E1”
    CASE 30 TO 34
