MASTERY CGPA CALCULATION @EASE of 5.00 Grading System.

Hello guys,
For those who are using the grades A, B, C, D, E and F. This is how it is been calculated. The table below shows the points associated with the grades.

Grade	Point
A	5
B	4
C	3
D	2
E	1
F	0

Scores and the deserved grade is seen in the table below

Score	Grade
70 - 100	A
60 - 69	B
50 - 59	C
45 - 49	D
40 - 44	E
0 - 39	F

CGPA and the class of degree associated with it. I will also use a table to present this information so that it will be more clear to us all.

CGPA	Class of Degree
4.50 - 5.00	First Class
3.50 - 4.49	2nd Class Upper
2.40 - 3.49	2nd Class Lower
1.50 - 2.39	3rd Class
1.00 - 1.49	Pass

Some Terminologies that need to be understood before you can be able to properly calculate your class of degree.

WHAT IS CGPA & GPA?

The acronym CGPA stands for - Cumulative Grade Point Average. (This is what you have after both 1st and 2nd semester .... In summation and Division, amounting to it)

GPA - Grade Point Average ( This is what you have after every semester)

C.U - Credit Units

TCU - Total Credit Unit

G.P - Grade Point

TGP or TQP - Total Grade Point or Quality Point

HOW TO CALCULATE GPA:

GPA can be calculated by dividing the Total Grade/Quality point (TQP/TGP) by the Total Credit unit (TCU) for that semester.

For example:

If in a semester, a student earned 90 quality points for 21 credit units, the GPA will be;

GPA = TGP/TCU

90/21

=4.28

HOW TO CALCULATE CGPA:

CGPA is derived by adding the Total Quality Points (TQP) for all the semesters to date and dividing by the Total Credit Units to date for all semester... 1st & 2nd.

For example:
If in a semester a student earns a QP of 90 for 21 CU in the first semester and earns a QP of 87 for 20 CU in the second semester, His/Her CGPA will be ;

CGPA = TQP/TCU

= (90 + 87)/(21 + 20)

= 177/41

= 4.31

Your CGPA for that session will be, CGPA = 4.31

For more clearity let me explain it using a sample result of one Mr. Okponor from the federal university Uyo. Mr. Okponor is a computer science student and he registered and had the following grade in his exams. This is his first semester result below.

S/No.	Course Code	Units	Grade	GP
01.	CSC 101	3	A	15
02.	Csc 111	2	B	8
03.	Csc 103	1	C	3
04.	Csc 107	3	D	6
05.	Csc 117	2	E	2
06.	Csc 171	1	F	0

TCU = 12

TGP = 34

Therefore his result for the semester will be

GPA = 34/12

GPA = 2.83

Let us now consider 2nd Semester Result. NB: We'd carry out same procedure in 1st semester then apply here. But let's assume our TCU & TGP to be = 20 and = 93 respectively.

GPA for second semester GPA = TGP/TCU

GPA = 93/20

GPA = 4.65

We have successful gotten GPA for first and second semester respectively. So to get the CGPA, follow the procedure below.

Mathematically;

CGPA = TGP+TGP(1st & 2nd semester) / TCU+TCU(1st & 2nd Semester)

CGPA = 34+94/ 12+20

CGPA = 128 / 32 = 4.00

NB: Always approximate your point to 2 decimal places.

Thus: Your main
CGPA = 4.00

I hope this goes a long way in explaining how this is calculated. For any question or doubt please use the comment section. Thank you for your time.
