The level of your academic success is based on the value of your grade point average (GPA) at the end of a semester and at the end of every academic session. So, there is every need for each student to know his level of academic success by computing his GPA or CGPA (cumulative grade point average) up to date. Here is how to compute your GPA per semester and CGPA per session to enable your know your academic success.
First, you should know the credit load (weight) of each of your courses for the semester and for the session. Next, you should know the points attached to a grade in a course. Then, you calculate the total points for a course by multiplying the points attached to a grade in a course by the credit load of the course. For example, if the credit load of a course is 2 and you score a grade whose point is 4, then the total points you have for that course is 8 (that is, 2 x 4 = 8).
After computing the total points for each course, you then add together the total points of all the courses for a semester or for a session. You also sum up the total credit loads of all the courses for the semester or session. Divide the total points of the courses for the semester or session by the total credit loads for the semester or session. The result is your GPA for the semester or CGPA for the academic session.
In universities, especially new-generation universities, the following are the course grades and points attached to them:-
A => 5 points, B => 4 points, C => 3 points, D => 2 points, E => 1 point, and F => no point.
Let’s assume that in the first semester, you offered 3 courses and your grades are as follows:
GST101, 2 credits, score B (4 points)
CSC201, 3 credits, score A (5 points)
MAT203, 2 credits, score C (3 points)
Then, GPA for the first semester will be calculated thus:
GST101, total points = 2 x 4 = 8
CSC201, total points = 3 x 5 = 15
MAT203, total points = 2 x 3 = 6
Total points for the semester = 8 + 15 + 6 = 29.
Total credit loads for the semester = 2 + 3 + 2 = 7.
First semester GPA = 29 / 7 = 4.143.
Let’s assume that in second semester, you offered the following 4 courses;
GST102, 1 credits, score A (5 points)
CSC202, 2 credits, score A (5 points)
MAT204, 2 credits, score E (1 point)
CSC242, 4 credits, score D (2 points)
Then, GPA for the second semester will be calculated as follows:
GST102, total points = 1 x 5 = 5
CSC202, total points = 2 x 5 = 10
MAT204, total points = 2 x 1 = 2
CSC242, total points = 4 x 2 = 8
Total points for the semester = 5 + 10 + 2 + 8 = 25.
Total credit loads for the semester = 1 + 2 + 2 + 4 = 9.
Second semester GPA = 25 / 9 = 2.778.
Then, for the academic session (first semester and second semester), the total points = 29 + 25 = 54, and the total credit loads = 7 + 9 = 16.
Session CGPA = 54 / 16 = 3.375.
That is all for it. Very simple. Try it to know your level of academic success per semester and per session.
Note: Some university use different grading system, but the GPA and CGPA computations are basically the same.
