Nigerian Polytechnics Grading System

Mark (%) Letter Grade Grade Point FINAL CGPA Class of Degrees
100 – 80 A 4.00 3.50 – 4.00 Distinction
79 – 70 AB 3.50 3.00 – 3.49 Upper Credit
69 – 60 B 3.00 2.50 – 2.99 Lower Credit

First Semester OND1 GPA Calculation

In the polytechnic, if a student offers the following courses and obtains a score that corresponds to the following letter grades that lead to the distribution on the tables below.

Bearing in mind that GPA cannot be approximated then such student will calculate his/her GPA as follows:

Course Code Credit Unit Letter Grade Points Grade Credit x Points Total Points
GSP 101 2 C 2.00 2 x 2.00 4.00
GSP 111 2 A 4.00 2 x 4.00 8.00
GSP 105 2 C 2.00 2 x 2.00 4.00
GSP 201 2 AB 3.50 2 x 3.50 6.50
COS 101 2 BC 2.50 2 x 2.50 4.50
STA 131 2 B 3.00 2 x 3.00 6.00
MTH 221 3 C 2.00 3 x 2.00 6.00
Total Credit Units 15 Total Points 39.00

 

First Semester OND1:

GPA = Total points/Total Credit Units = 39.00/15 = 2.6.
Therefore his/her first semester ND1 GPA = 2.6.

First Semester OND1 GPA Calculation/Computation Table:

Course Code Credit Unit Letter Grade Points Grade Credit x Points Total Points
CHM 112 2 A 4.00 2 x 4.00 8.00
GSP 208 2 E 0.00 2 x 0.00 0.00
GSP 106 2 C 2.00 2 x 2.00 4.00
GSP 202 2 C 2.00 2 x 2.00 4.00
BIO 152 3 B 3.00 3 x 3.00 9.00
PHY 196 2 BC 2.50 2 x 2.50 4.50
GLG 142 3 C 2.00 3 x 2.00 6.00
Total Credit Units 16 Total Points 35.5

 

Second Semester GPA = Total points/Total Credit Units = 35.50/16 = 2.21875= 2.21.
Therefore his/her second semester ND1 GPA = 2.21.

To calculate here cumulative grade point average (CGPA) for ND1 (first year), such student add his/her ND1 first semester and second semester GPA and divide the result  obtained by two (2), i.e. the number of semester.

Here is the working on how to calculate the g.p of polytechnic:

The student’s OND1 CGPA = (First Semester ND1 GPA + Second semester ND1 GPA) / 2 = (2.6 + 2.21) / 2.

CGPA = 4.81 / 2 = 2.405 = 2.40 

The finale CGPA = (OND1 + OND2) / 2 = (2.40 + 3.45) / 2 = 5.85 / 2 = 2.925 = 2.92.

FCGPA = 2.92.


That is it on the The BEST and EASIEST way to calculate CGPA in a Nigerian POLYTECHNIC.
