How to calculate GPA for first semester OND 1

Let’s assume you offer the courses (listed below) and obtain grades as depicted in the table. The GPA can be calculated thus:

Course Code Credit Unit Grade Grade Points Quality Points (CU X GP) Total Points
GSP 101 3 A 4.00 2 X 4.00 8.00
GSP 105 2 B 3.00 2 X 3.00 6.00
GSP 111 2 C 2.00 2 X 2.00 4.00
GSP 201 2 C 2.00 2 X 2.00 4.00
COS 101 2 AB 3.50 2 X 3.50 7.00
STA 131 2 B 2.00 2 X 2.00 4.00
MTH 221 2 BC 2.50 2 X 2.50 5.00
TOTAL CREDIT UNITS 15 38

To calculate the first semester OND 1, use the following formula:

GPA = Total Points/ Total Credit Units =38/15 = 2.5

The first semester GPA is, therefore 2.5

How to calculate GPA for second semester OND 1

Let’s assume you offer the courses (listed below) and obtain grades as depicted in the table. The GPA can be calculated thus:

Course Code Credit Unit Grade Grade Points Quality Points (CU X GP) Total Points
 GLG 142 2 AB 3.50 2 X 3.50 7.00
 GSP 208 2 B 2.00 2 X 2.00 4.00
 GSP 202 2 C 2.00 2 X 2.00 4.00
 PHY 196 3 C 2.00 2 X 2.00 4.00
 GSP 106 2 BC 2.50 2 X 2.50 5.00
 CHM 112 2 B 2.00 2 X 2.00 4.00
 GSP 106 3 B 3.00 2 X 3.00 6.00
TOTAL CREDIT UNITS 16 34

To calculate the second semester OND 1, use the following formula:

GPA = Total Points/ Total Credit Units =34/16 = 2.1

The second semester GPA is, therefore 2.1

To calculate the cumulative grade point average (CGPA) for National Diploma (ND) 1, add the GPA of the first and second semesters and divide by 2 (the number of semesters). This is calculated to obtain the average.

The calculation goes thus:

OND 1 CGPA = (First Semester ND 1 GPA + Second Semester ND 1 GPA) / 2 = (2.5 + 2.1) / 2

CGPA = 4.6 / 2 = 2.3

Explanation of each Grade Level in a Polytechnic Setting

3.50 – 4.00 CGPA attracts a ‘Distinction’ class of degree. This is synonymous to a First Class degree in a Nigerian university.

Upper Credit class of degree is awarded to a student with 3.00 – 3.49 CGPA. This is synonymous with Second Class Honours (Upper Division) in Nigerian universities.

2.0 – 2.00 CGPA attracts a ‘Lower Credit’ degree. This is synonymous with a ‘Second Class Honours’ (Lower Division) in Nigerian universities.

The same explanation goes for the ‘Pass’ and ‘Fail’ classes of degrees.
