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 we don’t approximate GPA 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 so obtain by two (2), i.e. the number of semester.
Here is the working:
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.
