In NUC standard, our higher institutions make use of Cumulative Grade Point Averages to measure Academic Excellence. A [symple_highlight color=”blue”]Students Nigeria[/symple_highlight] writer is going to teach you how to calculate CGPA in Nigerian Universities. It is vital that all university students, especially Freshers, study and learn how to calculate their GPA upon release of each semester’s result and to also make up the cumulative at the end of every session. Doing this will help you evaluate your academic performance from time to time and improve.

Performance in semester examinations and assessments for courses/subjects/modules are classified into letter Grades (from A, B, C, D, E, to F) which represent a range of score or marks a student can obtain. A particular grade point is assigned to these grades, see below.

Calculating Your Grade Point Average (GPA)
Every Course/subject/module carries a fixed number of Credit Units (CU). Quality points (QP) are derived from multiplying the Credit Units (CU) for a course by the Grade Point (GP) earned by the student in that course.

Eg. If in a 3 Credit Unit course, a student scores 63% which is a B with a Grade Point of 4, the Quality points for the student in that course is 3 x 4 = 12.

Grade Point Average (GPA) is derived by dividing the Total Quality point (TQP) for the semester by the Total Credit Unit (TCU) for that semester.

Eg. If in a semester, a student earned 56 quality points for 18 Credit Units, the students GPA is 56/18 = 3.11

Cumulative Grade Point Average (CGPA) is derived by adding the Total Quality Points (TQP) for all semesters to date and dividing by the Total Credit Units (TCU) for all semesters to date.

Eg. If a student earns a QP of 56 for 18 CU in the first semester and earns QP of 67 for 20 CU in the second semester, His CGPA is TQP/TCU = (56 + 67) / (18 + 20) = 123/38 =3.24

Below is a detailed example of how to calculate GPA and CGPA

QP = 66, CU = 17, TQP = 66, TCU = 17

GPA = QP/CU = 66/17 = 3.88

CGPA = TQP/TCU = 66/17 = 3.88

QP = 48, CU = 20, TQP = 66 + 48 = 114, TCU = 17 + 20 = 37

GPA = QP/CU = 48/20 = 2.40

CGPA = TQP/TCU = 114/37 = 3.08

NB: This Procedure is repeated for following years until your final year in school (graduation).
