How to calculate GPA

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 CodeCredit UnitLetter GradePoints GradeCredit x PointsTotal Points
GSP 1012C2.002 x 2.004.00
GSP 1112A4.002 x 4.008.00
GSP 1052C2.002 x 2.004.00
GSP 2012AB3.502 x 3.506.50
COS 1012BC2.502 x 2.504.50
STA 1312B3.002 x 3.006.00
MTH 2213C2.003 x 2.006.00
Total Credit Units15Total Points39.00

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 CodeCredit UnitLetter GradePoints GradeCredit x PointsTotal Points
CHM 1122A4.002 x 4.008.00
GSP 2082E0.002 x 0.000.00
GSP 1062C2.002 x 2.004.00
GSP 2022C2.002 x 2.004.00
BIO 1523B3.003 x 3.009.00
PHY 1962BC2.502 x 2.504.50
GLG 1423C2.003 x 2.006.00
Total Credit Units16Total Points35.5

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.
