How to Calculate CGPA in Nigerian Universities

The calculation of CGPA at the University sounded like complex mathematics work.

Some students had to pay senior students for the calculation of their results.

Well, the calculation of CGPA is not a complex mathematics problem. It is easy, and you can do it yourself by following the steps in this post.

In this post, I will be showing you the easy way that you can use to calculate the GPA for your first and second semesters. You will learn how to calculate GPA from CGPA.

Also, you will know how to calculate CGPA in Nigerian Universities like the University of Ibadan, UNN, AAU, UNILAG, NOUN, OAU, UNIPORT, UNILORIN, etc. and other tertiary institutions in Nigeria.

Note that the method for calculating GPA and CGPA in all Nigerian Universities is the same as the procedures here.

First-year and other students will find this post helpful. But first, let me explain the meaning of GPA and CGPA in Nigerian Universities.

Let me know in the comment box if you need clarification. I will get back to you as soon as possible.

Nigerian University Grading System

The grading system in Nigeria’s tertiary institutions uses over a hundred scores.

Thirty (30) marks are for continuous assessment, while seventy (70) is for examination scores.

Test scores, assignment and class presentation makes up your continuous assessment.

Here is the grading system for Nigerian Universities;

Score	Grade	Points	Remark
70 – 100	A	5	Excellent
60 – 69	B	4	Very Good
50 – 59	C	3	Good
45 – 49	D	2	Pass
40 – 44	E	1	Fair
0 – 39	F	0	Fail

GPA

GPA stands for grade point average. It is the grade point for your first and second-semester results.

You need to know your course score to calculate either semester’s GPA.

Below is a sample of a first-year student’s first and second-semester results at the University.

MAN 101	Principles of Small Business Economics	2
MTH 111	General Mathematics I	3
MAN 141	Elements of Business Economics I	3
GSP 101	The Use of English I	2
GSP 105	Natural Science I	2
Total		19

First Semester Result

Course Code	Course Title	Score	Grade
ACC 101	Elements of Accounting I	46	D
COS 101	Introduction to Computer Science	75	A
PHI 101	Introduction to Logic	66	B
MAN 101	Principles of Small Business Economics	43	E
MTH 111	General Mathematics I	54	C
MAN 141	Elements of Business Economics I	87	A
GSP 101	The Use of English I	49	D
GSP 105	Natural Science I	57	C

First Semester GPA Calculation

Course Code	Unit	Grade	Point	Unit x Point	Total
ACC 101	2	D	2	2 x 2	4
COS 101	3	A	5	3 x 5	15
PHI 101	2	B	4	2 x 4	8
MAN 101	2	E	1	2 x 1	2
MTH 111	3	C	3	3 x 3	9
MAN 141	3	A	5	3 x 5	15
GSP 101	2	D	2	2 x 2	4
GSP 105	2	C	3	2 x 3	6
Total	19	–	25	–	63

GPA Formula

The formula for calculating CPA is Quality Point/Credit Unit or Total/Unit

• Unit = Credit Unit
• Total = Quality Point

You will divide the total point by the total number of credit unit loads for the first semester.

• Total Quality Point (TQP) = 63
• Total Credit Uni (TCU) = 19
• GPA = 63/19 = 3.32

From our calculation, the CPA for the first semester is 3.32.

Now let us calculate the GPA for the second semester.

Second Semester Course Outline

Course Code	Course Title	Unit
ACC 102	Elements of Accounting II	2
PSY 101	Introduction to Psychology	2
BF 101	Introduction to Finance	2
MTH 112	General Mathematics II	2
MAN 142	Elements of Business Economics II	3
GSP 102	The Use of English II	2
GSP 106	Natural Science II	2
Total		15

Second Semester Result

The table below shows the second-semester result we would use for the calculation.

Course Code	Course Title	Score	Grade
ACC 102	Elements of Accounting II	65	B
PSY 101	Introduction to Psychology	56	C
BF 101	Introduction to Finance	44	E
MTH 112	General Mathematics II	59	C
MAN 142	Elements of Business Economics II	78	A
GSP 102	The Use of English II	49	D
GSP 106	Natural Science II	81	A

Second Semester GPA Calculation

Course Code	Unit	Grade	Point	Unit x Point	Total
ACC 102	2	B	4	2 x 4	8
PSY 101	2	C	3	2 x 3	6
BF 101	2	E	1	2 x 1	2
MTH 112	2	C	3	2 x 3	6
MAN 142	3	A	5	3 x 5	15
GSP 102	2	D	2	2 x 2	4
GSP 106	2	A	5	2 x 5	10
Total	15	–	23	–	51

You will divide the total point by the total number of credit unit loads for the second semester.

• Total Quality Point (TQP) = 51
• Total Credit Uni (TCU) = 15
• GPA = 51/15 = 3.4

From our calculation, the CPA for the first semester is 3.4.

Now, we can calculate the Cumulative Grade Point Average (CGPA).

I hope you have understood the calculations up to this point. Let me know in the comment if there is any confusion.

CGPA

CGPA stands for cumulative grade point average. It is an addition to your first and second semester GPA.

An academic session in the University comprises the first and second semesters.

The formula to calculate the CGPA is the summation of the Total Quality Point (TQP)/Total Credit Unit (TCU) for both semesters of the first year.

CGPA Formula = Σ TQP/TCU

First Year	Total Quality Point (TQP)	Total Credit Unit (TCU)
First semester	63	19
Second semester	51	15
Total	114	34

CGPA = Σ TQP/TCU

CGPA = 114 + 34 = 3.35

From our calculation, the CGPA for the first year is 3.35.

Now let us calculate the final CGPA for a four year course.

Final Year CGPA

The final year CGPA is an addition to your Total Quality Point and Total Credit Unit from the first to your last year.

For this calculation, I will sum the Total Quality Point (TQP) and Total Credit Unit (TCU) for each academic session.

Below is the CGPA of a student from the first year to the final year.

Level	Total Quality Point (TQP)	Total Credit Unit (TCU)
100	114	34
200	120	32
300	123	30
400	130	28
Total	487	124

Final CGPA = Σ TQP/TCU

Final CGPA = 487/124 = 3.93

From our calculation, the graduating CGPA is 3.93.

The same procedure applies to students studying a five (5) or six (6) years course at the University.

Nigerian Degree Categories

CGPA	Degree Category
4.50 – 5.0	First Class
3.50 – 4.49	Second Class (Upper)
2.50 – 3.49	Second Class Lower
Less than 2.49	Third Class
