GP: GRADE POINT; is derived from the actual percentage or raw score of a given course e.g Grade A = 4 Points, Grade B = 3 Points etc.

TGP: TOTAL GRADE POINT; is derived from multiplying the grade point by the units per course and summing up the grade points for all the courses registered.

TNU: TOTAL NUMBER UNITS; is obtained by adding up all the units of courses taken by the student in the semester.

GPA: GRADE POINT AVERAGE; is the average of weighted grade obtained by dividing the TGP by the TNU for a semester.

CGPA: CUMULATIVE GRADE POINT AVERAGE; is the update average of the grade points earned by the student in programme of study. It is computed by adding the GPAs acquired by the student in the two semesters and then divided by 2.

TABLE 1: ASSUMED STUDENT’S GRADES IN HARMATTAN SEMESTER YEAR ONE

S/N	COURSE CODE	UNIT	GRADE	GRADE POINT
1	MTH 101	4	A	4 X 4 = 16
2	PHY 101	4	A	4 X 4 = 16
3	CHM 101	4	A	4 X 4 = 16
4	BIO 101	3	A	3 X 4 = 12
5	ENG 101	1	A	1 X 4 = 4
6	ENG 103	1	A	1 X 4 = 4
7	GST 101	2	A	2 X 4 = 8
8	GST 103	1	A	1 X 4 = 4
9	IGB 101	1	A	1 X 4 = 4
		TNU = 21		TGP = 84

From the table above, using the scale of 4 for grade A:

TNU = 21, TGP = 84

GPA = TGP/TNU = 84/21 = 4.00

TABLE 2: ASSUMED STUDENT’S GRADES IN RAIN SEMESTER YEAR ONE

S/N	COURSE CODE	UNIT	GRADE	GRADE POINT
1	MTH 102	4	A	4 X 4 = 16
2	PHY 102	4	C	4 X 2 = 8
3	CHM 102	4	B	4 X 3 = 12
4	BIO 102	2	F	3 X 0 = 0
5	ENG 102	1	C	1 X 2 = 2
6	GST 102	2	C	2 X 2 = 4
7	GST 108	2	B	2 X 3 = 6
8	GST 110	1	C	1 X 2 = 2
9	IGB 102	1	C	1 X 2 = 2
		TNU = 21		TGP = 52

From the table above, using the scale of 4 for grade A:

TNU = 21, TGP = 52

GPA = TGP/TNU = 52/21 = 2.48

CGPA = GPA(For Harmattan Semester)/GPA(For Rain Semester)

CGPA = 4.00/2.48 = 1.61 (THIRD CLASS)
