The Cumulative Grade Point Average (CGPA) is a measure of a student’s overall academic performance at Olabisi Onabanjo University. It reflects the average of all grade points earned across all semesters and courses taken since admission.
OOU uses the 4-point grading system, which assigns numerical grade points to letter grades as follows:
Step-by-Step Guide to Calculating CGPA
Step 1: Know Your Course Units
Each course carries a certain number of credit units (e.g., 2-unit, 3-unit, etc.). These units represent the course’s academic weight.
Step 2: Determine Your Grade Point for Each Course
Using the table above, find the Grade Point (GP) corresponding to your score in each course.
For example:
- If you scored 75% in a 3-unit course, your GP = 4.00.
- If you scored 58% in a 2-unit course, your GP = 2.40.
Step 3: Multiply Course Units by Grade Points
For each course, multiply the credit units by the grade point to get the Quality Points (QP).
Quality Points (QP)=Credit Units×Grade Point\text{Quality Points (QP)} = \text{Credit Units} \times \text{Grade Point}
Example:
If a 3-unit course has a GP of 3.50 (B grade), then:
3 × 3.50 = 10.5 Quality Points
Step 4: Add Up All Quality Points and All Credit Units
Sum up all Quality Points (QP) and all Credit Units (CU) for the semester or session.
Example:
If you took 5 courses with a total of 15 credit units and earned a total of 45 quality points, then:
- Total QP = 45
- Total CU = 15
Step 5: Calculate the GPA for the Semester
Divide the total quality points by the total credit units.
GPA=Total Quality PointsTotal Credit Units\text{GPA} = \frac{\text{Total Quality Points}}{\text{Total Credit Units}}
Example:
45 ÷ 15 = 3.00 GPA
Step 6: Calculate the Cumulative GPA (CGPA)
Your CGPA is the average of your GPAs across all semesters completed.
CGPA=Total Quality Points for All SemestersTotal Credit Units for All Semesters\text{CGPA} = \frac{\text{Total Quality Points for All Semesters}}{\text{Total Credit Units for All Semesters}}
For instance:
If after four semesters you have accumulated 180 quality points from 60 credit units,
then:
180 ÷ 60 = 3.00 CGPA
Step 7: Interpret Your CGPA
The CGPA determines your academic standing or class of degree as follows:
Example Summary
Total CU = 13
Total QP = 40.10
GPA=40.1013=3.08\text{GPA} = \frac{40.10}{13} = 3.08
CGPA after multiple semesters is then computed cumulatively using the same method.
Final Note
Students are encouraged to consistently monitor their GPA each semester to stay aware of their academic progress. Maintaining a strong CGPA is essential for graduation, scholarships, and postgraduate opportunities at OOU.
