Since now you know what CGPA stands for, we can tell you how to calculate CGPA from your marks.

In order to calculate your CGPA, you need the Credit Units of each course.

You also need your grade points for each of the five subjects. In order to make life easier,

we will remind you about the scaling in Nigerian Universities: –

The mark of 70% and above equals the letter grade of A or 5.00 Grade Points. –

The mark of 60-69% equals the letter grade of B or 54.00 Grade Points. –

The mark of 50-59% equals the letter grade of C or 3.00 Grade Points. –

The mark of 45-49% equals the letter grade of D or 2.00 Grade Points. –

The mark of 40-44% equals the letter grade of E or 1.00 Grade Points. –

The mark of 0-39% equals the letter grade of F or 0.00 Grade Points.

The next step is to calculate the Quality Point (QP).

In order to do it,

multiply the number of Credit Units by your Grade Points for the course.

For example, a course has four credit units,

and you’ve scored the mark of 72% that equals 5 Grade Points.

The Quality Point for this course will be 4 x 5 = 20.

To calculate your Cumulative Grade Point Average, you need to add the Total Quality Points for all semesters to date and divide the sum by the Total Credit Units (TCU) for all semesters to date.

For example, you earned 56 Quality Point for 18 Credit Units in your first semester.

Then you studied harder and received 67 Quality Point for 20 Credit Units in the second.

Your CGPA will be (56 + 67) / (18 + 20) = 123/38 =3.24

Now you know how to calculate CGPA – formula will help you.

It is quite easy, and now you can calculate your CGPA on your own.

Also, did you know that your CGPA will be reflected in your Grade Card? Good luck with your calculations!
