# How To Calculate Grade Points Average (GPA) And CGPA In Nigerian Universities

This is How To Calculate Grade Points Average (GPA) And CGPA In Nigerian Universities: It is very important for students especially freshers to know how to calculate their GPA upon release of each semester’s result and to also sum up the cumulative average at the end of each session. Performance in various courses in tertiary institutions in Nigeria are classified into letter grades ranging from A to F which stands for the range of score attainable by a student. Study the table below to see the particular grade points and remarks assigned to each score range :

 SCORE(%) GRADES GRADE POINTS REMARKS 70-100 A 5 Excellent 60-69 B 4 Very Good 50-59 C 3 Good 45-49 D 2 Fair 40-44 E 1 Pass 0-39 F 0 Fail

At the end of each semester, a student’s grade point average is worked out using the above grading system.

## HOW TO CALCULATE GRADE POINTS AVERAGE (GPA) IN NIGERIAN UNIVERSITIES

Bearing in mind that all courses have their fixed number of credit units (CU) . By multiplying a particular course’s credit unit by the grade point of your score, you get the Quality Point (QU) for the course.

For instance : Assuming MTH101 is a 5units course and you have a B grade in the course which amounts to a grade point of 4 ( Refer to the table above to check the grade points for each grade). Your quality point in that course is 5 x 4 = 20 i.e Quality point = Grade Point x Credit Unit .

Total Quality Point ( QP ) : Is obtained by adding all the quality points of the courses you offered for that semester.

Total Credit Unit ( CU ) : Is obtained by adding all the credit units of the courses you offered for that semester.

Grade Point Average ( GPA ) : Is obtained by dividing the total quality point by the total credit unit for that semester.

e.g In a semester, you got a total of 82 quality points and 18 credit units, your GPA for that semester is 82/18 which is 4.55.

Cumulative Grade Point Average ( CGPA ) : Is obtained by adding the total quality points for all semesters till date and dividing it by the total credit units for all semesters till date.

e.g Part One 1st semester – 82 QP and 18 CU
Part One 2nd semester – 77 QP and 19 CU
Part Two 1st semester – 80 QP and 17 CU
Part Two 2nd semester – 72 QP and 16 CU

Your Cumulative Grade Point Average (CGPA) at the end of part two will be the addition of all total quality units ( 82 + 77 + 80 + 72 ) divided by the addition of all total credit units ( 18 + 19 + 17 +16 ) => 311/70 = 4.44 .

Therefore your Cumulative Grade Point Average (CGPA) at the end of part two is 4.44!!! You should receive a standing ovation for that though, just a couple more efforts and first class is up for grabs for you.

Let’s take a comprehensive instance as we imagine the following results for first and second semester for a student in one of the universities in Nigeria :

First Semester

 Course Code Credit Unit Grade Grade Points Quality Points (CU X GP) Mth 101 5 A 5 25 Phy 101 4 B 4 16 Chm 101 4 A 5 20 Tpd 101 1 A 5 5 Csc 101 2 B 4 8 Chm 103 1 A 5 5 Phy 107 1 A 5 5 Total 18 84

For the first semester :
QP = 84 ; CU = 18
TQP = 84 ; TCU = 18
GPA = QP/CU = GPA = 84/18 = 4.67
CGPA = TQP/TCU = 84/18 = 4.67

Second Semester :

 Course Code Credit Unit Grade Grade Points Quality Points (CU X GP) Mth 102 5 C 15 15 Phy 102 4 A 5 20 Chm 102 4 B 4 16 Csc 102 2 A 5 10 Mth 104 2 D 2 4 Chm 105 1 A 5 5 Phy 108 1 A 5 5 Total 19 75

For the second semester:
QP = 75 ; CU = 19
TQP = 84 + 75 = 159 ; TCU = 18 +19 = 37
TQP =75 ; TCU = 19
CGPA = TQP/TCU = 159/37 = 4.30

Therefore, the Cumulative Grade Point Average (CGPA) for the two semesters is 4.30. The process is repeated for every semester result.

NOTE : Some courses with or without credit units are not to be involved in GPA and Cgpa calculations. Such courses are referred to as special electives and they have no impact on your grade points, you only need to avoid a ‘fail’ in such courses.

That should be all on how to calculate GPA (Grade Point Average) and CGPA (Cumulative Grade Point Average).
