# GPA and CGPA ▷ Calculate in Nigerian University + Polytechnic

As a Nigerian student, do you want to learn the grading system to calculate your GPA and CGPA score in university, polytechnic, secondary school, and high school using the 4.0 and 5.0 scale?

If you want to excel in your studies and graduate with a good grade, then knowing how to calculate GPA and CGPA in school is vital.

Today, you will know how to calculate CGPA for students schooling at the University of Ibadan, UNN, AAU, UNILAG, NOUN, OAU, UNIPORT, IMSU, UNIZIK, UNILORIN, and other tertiary institutions in Nigeria.

For this article, I will use the 5.00 GPA scale to teach you how to calculate your GPA and CGPA because it is the most widely used grading scale in Nigerian universities.

If your school uses 4.00, the calculation remains the same.

Getting started…

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

30 marks are for continuous assessment, while 70 marks is for examination scores.

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

Here is the grading system for universities in Nigeria:

 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

## What is GPA?

GPA, which means Grade Point Average, is a measure of a student’s academic achievement at a college or university.

The Grade Point Average is calculated by dividing the Total Grade Points by the Total Course Units received.

The formula for calculating the GPA is TGP/TCC.

Your GPA is important, as it shows how low or high you scored in your courses on average.

It is used to assess whether you meet the standards and expectations set by the degree programme or university.

To teach how to calculate your GPA and CGPA today, I’ll be using a sample of a biochemistry university student 100L and 200L first and second-semester results.

### GPA Formula

To get your GPA, you will divide the total points by the total number of credit unit loads for the semester.

Total Quality Point (TQP) = 81

Total Credit Unit (TCU) = 20

GPA = 81/20 = 4.05

From our calculation, the GPA for the 100 Level First Semester is 4.0.

Now let us calculate the GPA for the 100 Level Second Semester.

100 Level Second Semester GPA Calculation

 Course Code Unit Grade Point Unit x Point Total BIO 102 3 A 5 3 x 5 15 BIO 112 1 B 4 1 x 4 4 PHY 102 3 C 3 3 x 3 9 CHE 102 3 B 4 3 x 4 12 CHE 142 1 B 4 1 x 4 4 MAT 102 3 B 4 3 x 4 12 GST 102 2 B 4 2 x 4 8 GST 104 2 C 3 2 x 3 6 GST 106 2 A 5 2 x 5 10 GST 108 2 B 4 2 x 4 8 Total 22 – 40 – 88

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

Total Quality Point (TQP) = 88

Total Credit Unit (TCU) = 22

GPA = 88/22 = 4.0

From our calculation, the GPA for the 100 Level Second Semester is 4.0.

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

## What is CGPA?

CGPA, which means Cumulative Grade Point Average, is the Total Grade Point Earned divided by the Total Credit Units.

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

The difference between GPA and CGPA is that the GPA covers shorter periods, like one term or a semester.

While CGPA refers to the average grades got by a student at the end of two (2) or more semesters or throughout the entire academic experience.

 First Year (100L) Total Quality Point (TQP) Total Credit Unit (TCU) First Semester 81 20 Second Semester 88 22 Total 169 42

CGPA = Σ TQP/TCU

CGPA = 169/42 = 4.02

From our calculation, the CGPA for the first year (100 level) is 4.02.

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

### Final Year CGPA

The final year CGPA is an addition of 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.

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

 Level Total Quality Point (TQP) Total Credit Unit (TCU) 100 169 42 200 151 45 300 137 31 400 125 29 Total 582 147

Final CGPA = Σ TQP/TCU

Final CGPA = 582/147 = 3.96

From our calculation, the graduating CGPA is 3.96.

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

### Degrees Classification in Nigerian Universities

 Degree Cumulative Grade Point Average First Class Honours 4.5 – 5.0 Second Class Honours (Upper Division) 3.5 – 4.49 Second Class Honours (Lower Division) 2.49 – 3.49 Third Class Honours 1.50 – 2.48

### Final Words

Getting a good GPA makes you eligible to graduate with good honours and it increases your chances of getting better grants and scholarship.

The method for calculating GPA and CGPA in all Nigerian universities for first-year and other students is the same as explained in this post.

I wish you success.
