How to Calculate for CGPA in Nigerian Universities

Doing the calculations for GPA and CGPA is very straight and simple if you follow the steps properly. We have explicate down all the procedures, but first, let's enlighten on the terms used that may seem unfamiliar.

Basic terms to note in calculating for CGPA.

Credit Unit (CU) – This is a fixed unit attached to a course. This units is always done due to its importance as more tougher courses seem to have higher credit units. Example: Basic Statistics and Probability = 3 units.
GP (Grade Point) – This is a point allocated to a letter notation A, B, C, D, E and F.
GPAv(Grade Point Average) – The calculated point average a student earned per semester.
CGPA – The cumulative grade point earned from the beginning of study till the final year of course.

Calculating for CGPA is not much complex task. Here is the grading system used to calculate CGPA.

Mark/Score| Letter Notation| Grade Point(GP)
70-100 A 5.0
60-69 B 4.0
50-59 C 3.0
45-49 D 2.0
40-44 E 1.0
0-39 F 0.0
Note: This grade point is based on a 5.0 grading scale only.

How CGPA is calculated

Credit Unit (CU) are fixed to all courses and it signifies the value of the course.
The Grade point average(GPA) which is the calculated performance of a student, is derived by dividing the total grade points for a semester by the credit unit for that semester. Consider Ali to have earned 56 grade point as his quality point for a 20 credit unit. When you divide the total grade points 56 by the sum of credit units 20. The answer will be = 2.8 which will put Ali in a second class lower using a 5.0 grading scale.

Cumulative Grade Point Average (CGPA) is gotten by the summing of all the grade point average and dividing by n(number of GPAs). It is also derived by adding the total quality point and then dividing it by the Total Credit units for the courses offered.

If you are offering a four year degree programme, to calculate your CGPA for the four years, just do GPA(year 1)+GPA(year 2)+GPA(year 3)+GPA(year 4) divided by the credit units CU(year 1)+CU(year 2)+CU(year 3)+CU(year 4) and get your graduating CGPA.
Similarly, 5 year degree programmes like Engineering, Nursing, Medical Laboratory can get their CGPA by adding the respective GPA and TCU (Total Credit Units) for the fifth year of study.
