How to Calculate CGPA in Nigerian Universities

Calculate CGPA

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;

ScoreGradePointsRemark
70 – 100A5Excellent
60 – 69B4Very Good
50 – 59C3Good
45 – 49D2Pass
40 – 44E1Fair
0 – 39F0Fail

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.

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.

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 YearTotal Quality Point (TQP)Total Credit Unit (TCU)
First semester6319
Second semester5115
Total11434

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.

LevelTotal Quality Point (TQP)Total Credit Unit (TCU)
10011434
20012032
30012330
40013028
Total487124

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.
